Sebastian Huber 8a5af1a184 Use __machine_*_t_defined for internal types
Newlib defines defaults for internal types via <sys/_types.h> and uses
<machine/_types.h> to let targets define their own type if necessary.

Previously for example

	#ifndef __dev_t_defined
	typedef short __dev_t;
	#endif

However, the __*_t_defined pattern conflicts with the glibc type guard
pattern for user types, e.g. dev_t in this example.  Introduce a
__machine_*_t_defined pattern for internal types (defined by
<machine/_types.h>, used by <sys/_types.h>).  For example

	#ifndef __machine_dev_t_defined
	typedef short __dev_t;
	#endif

Yaakov Selkowitz 9f90ae0435 Feature test macros overhaul: string.h and strings.h overlaps
strings.h is the header mandated for these functions in POSIX.1 prior to
2008 (when most of these were removed).  The declarations in string.h are
only for BSD compatibility.  But when both headers are included, avoid
duplicate declarations.

Also, mark stpcpy and stpncpy as POSIX.1-2008.

Sebastian Huber 477463a201 Eliminate use of Newlib-specific <machine/types.h>
This change solves a glibc/BSD compatibility problem.

glibc and BSD use double underscore types for internal types.  The Linux
port of Newlib uses some glibc provided internal type definitions which
are not protected by guard defines, e.g. __off_t.  To avoid a conflict
Newlib uses single underscore types for some internal types, e.g.
_off_t.  However, for BSD compatibility we have to define the internal
types with double underscore names in <sys/_types.h>.

The header file <machine/types.h> is Newlib-specific.  It was used
instead of <sys/_types.h> to provide the internal type definitions
_CLOCK_T, _TIME_T_, _CLOCKID_T_, _TIMER_T_, and __suseconds_t.  Move
these definitions to <sys/_types.h> (there exist two instances of this
file, one for Linux and one for all other targets).  This makes the
_HAVE_SYSTYPES configuration define obsolete (could possibly break the
__RDOS__ target).  Use the standard <sys/_types.h> include throughout.

Move __loff_t defintion to default (non-Linux) <sys/_types.h>.  Define
it via _off64_t to avoid a dependency on the compiler.

Provide the __off_t definition via default (non-Linux) <sys/_types.h>
based on _off_t for all systems except Cygwin.  For Cygwin use _off64_t.
Define off_t via __off_t.

Provide the __pid_t definition via default (non-Linux) <sys/_types.h>.
This prevents a potential __pid_t and pid_t incompatibility.  Add BSD
guard defines for pid_t.

Corinna Vinschen e185421106 strxfrm/wcsxfrm: Always return length of the transformed string
Cygwin's strxfrm/wcsfrm treated a too short output buffer as an error
condition and always returned the size value provided as third parameter.
This is not as it's documented in POSIX.1-2008.  Rather, the only error
condition is an invalid input string(*).

Other than that, the functions are supposed to return the length of the
resulting sort key, even if the output buffer is too small.  In the latter
case the content of the output array is unspecified, but it's the job
of the application to check that the return value is greater or equal to
the provided buffer size.

(*) We have to make an exception in Cygwin:  strxfrm has to call the
    UNICODE function LCMapStringW for reasons outlined in a source comment.
    If the incoming multibyte string is so large that we fail to malloc
    the space required to convert it to a wchar_t string, we have to
    ser errno as well since we have nothing to call LCMapStringW with.

	* nlsfuncs.cc (wcsxfrm): Fix expression computing offset of
	trailing wchar_t NUL.  Compute correct return value even if
	output buffer is too small.
	(strxfrm): Handle failing malloc.  Compute correct return value
	even if	output buffer is too small.

Johannes Schindelin 03ecfb9280 Be truthful about reporting whether readahead is available
In 7346568 (Make requested console reports work, 2016-03-16), code was
introduced to report the current cursor position. It works by using a
pointer that either points to the next byte in the readahead buffer, or
to a NUL byte if the buffer is depleted, or the pointer is NULL.

These conditions are heeded in the fhandler_console::read() method, but
the condition that the pointer can point at the end of the readahead
buffer was not handled properly in the get_cons_readahead_valid()
method.

This poses a problem e.g. in Git for Windows (which uses a slightly
modified MSYS2 runtime which is in turn a slightly modified Cygwin
runtime) when vim queries the cursor position and immediately goes on to
read console input, erroneously thinking that the readahead buffer is
valid when it is already depleted instead. This condition results in an
apparent freeze that can be helped only by pressing keys repeatedly.

The full Git for Windows bug report is here:

	https://github.com/git-for-windows/git/issues/711

Let's just teach the get_cons_readahead_valid() method to handle a
depleted readahead buffer correctly.

Yaakov Selkowitz 722e363c4d math: guard BSD finite/isinf/isnan functions properly in math.h
Now that we have properly functioning feature test macros, the BSD
floating-point classification functions can go into math.h instead of
the non-standard ieeefp.h, and not under the C99 guard:

http://man7.org/linux/man-pages/man3/finite.3.html

The isnan function was in earlier versions of SUS but removed starting with
POSIX.1-2001, compare:

http://pubs.opengroup.org/onlinepubs/007908799/xsh/math.h.html
http://pubs.opengroup.org/onlinepubs/009695399/basedefs/math.h.html

Note that the isinf and isnan functions (but not the variants) conflict
with functions by the same name in C++11, hence they (and only they)
need to be hidden:

Peter Foley e7e6119241 Rename without-mingw-progs to with-cross-bootstrap
Rename without-mingw-progs to with-cross-bootstrap, since it now
disables additional checks that are problematic for cross-compilers.

When cross-compiling a toolchain targeting cygwin, building cygwin1.dll
requires libgcc.
However, building libgcc requires the cygwin headers to be
installed.
Configuring cygwin requries the mingw-crt libraries, which require the
cygwin headers to be installed.
Work around this circular dependency by making the
--with-cross-bootstrap configure option skip cygwin's configure checks
for valid mingw-crt libraries. Cygwin will still properly link against
these libraries if they exist, but this allows configure to succeed even
if the libraries have not been built yet.
Since the mingw-crt libraries only require the cygwin headers to be
installed, this allows us to successfully configure cygwin so that we
can only install the headers without trying to build any
libraries.

Apart from some self-written additions (exp10l, finite{f,l}, isinf{f,l},
isnan{f,l}, pow10l) the files are taken from the Mingw-w64 math lib.
Minor changes were required, e.g. substitue _WIN64 with __x86_64__ and
fixing __FLT_RPT_DOMAIN/__FLT_RPT_ERANGE for Cygwin.

Cygwin:
	* math: New subdir with math functions.
	* Makefile.in (VPATH): Add math subdir.
	(MATH_OFILES): List of object files collected from building files in
	math subdir.
	(DLL_OFILES): Add $(MATH_OFILES).
	${CURDIR}/libm.a: Add $(MATH_OFILES) to build.
	* common.din: Add new functions from math subdir.
	* i686.din: Align to new math subdir.  Remove functions now commonly
	available.
	* x86_64.din: Ditto.
	* math.h: math.h wrapper to define mingw structs used in some files in
	math subdir.
	* include/cygwin/version.h: Bump API minor version.

newlib:
	* libc/include/complex.h: Add prototypes for complex long double
	functions.  Only define for Cygwin.
	* libc/include/math.h: Additionally enable prototypes of long double
	functions for Cygwin.  Add Cygwin-only prototypes for dreml, sincosl,
	exp10l and pow10l.  Explain why we don't add them to newlib.
	* libc/include/tgmath.h: Enable long double handling on Cygwin.

Corinna Vinschen 087aca6163 Fix Cygwin setstate definition
setstate is supposed to take a char *, not a const char *.

	* random.cc (setstate): Unconstify parameter to align to stdlib.h.

Yaakov Selkowitz 660f84b15b cygwin: export __getpagesize
The inclusion of <sys/cygwin.h> by <sys/shm.h>, besides causing namespace
pollution, also makes it very difficult to get the WINVER-dependent parts
of the former.  This affects code (such as x11vnc -unixpw_nis) which use
both SysV shared memory (e.g. the X11 MIT-SHM extension) and user password
authentication.

getpagesize is the simplest function to retreive this information, but it
is a legacy function and would also pollute the global namespace. The LSB
lists another form which is in the implementation-reserved namespace:

Joel Sherrill ecf453f963 Add simple versions of random() and srandom()
Prototypes also added for initstate() and setstate() but they
were not implemented in the shared newlib code.

	* newlib/libc/include/cygwin/stdlib.h: Prototypes added.
	* winsup/cygwin/include/cygwin/stdlib.h: Prototypes removed.
	* newlib/libc/stdlib/random.c: New file.
	* newlib/libc/machine/epiphany/machine/stdlib.h: Removed
	* newlib/libc/stdlib/Makefile.am: Added random.c.
	* newlib/libc/stdlib/stdlib.tex: Added random.def.
	* newlib/libc/stdlib/Makefile.in: Regenerated.

Corinna Vinschen 799fdda4d2 math.h: Use GCC builtins for C99 macros where available
GCCs builtin functions are mostly type agnostic and architecture
indepedent.  Prefer to use them if available.

	* libc/include/math.h (fpclassify, isfinite, isinf, isnan,
	isnormal): Use matching GCC builtin functions if built with
	GCC 4.4 or later.
	(signbit): Use matching GCC builtin functions if built with
	GCC 4.0 or later.
	(isgreater, isgreaterequal, isless, islessequal, islessgreater,
	isunordered): Use matching GCC builtin functions if built with
	GCC 2.97 or later.
