Commit 6f3943b erroneously removed the `#ifdef _COMPILING_NEWLIB'
guarding the __getreent inline function. This patch ignored the
fact that config.h is included when building applications, and the
code in question requires internal, auto-generated headers to be
available which are not exposed to user-space.
Reinstantiate defined(_COMPILING_NEWLIB) test and alternatively
check for defined (__INSIDE_CYGWIN__), otherwise we'd have to
reinstantiate the __getreent macro in cygtls.h which is really
confusing.
While testing it turned out that a low number of source codes inside
Cygwin won't see the inline __getreent due to a missing __INSIDE_CYGWIN__
definition. For malloc.cc this was actually deliberate to get different
definitions from including cygmalloc.h. Change this by defining
__INSIDE_CYGWIN__ in malloc.cc but changing the test in cygmalloc.h
to test for defined(DLMALLOC_VERSION). This might need a change if we
ever get around to replace dlmalloc with a newer, more threading-aware
malloc implementation.

This reverts commit 4de8596. It worked around a problem which was
actually introduced by patch 10a30e7 a few weeks ago. Rather than
adding special code to the newlib version of __getreent, the followup
patch reinstantiates the original, Cygwin-only implementation of
__getreent.

So far the lib function __getreent always returned _impure_ptr. On Cygwin
this is only correct after _impure_ptr got initialized. The inline
function in include/cygwin/config.h always returns the right _reent ptr,
though.
After introducing per-thread locales, the __getreent function is called
prior to initialization of _impure_ptr (from dll_crt0_0) to access the
locale pointer, which leads to a crash.
Fix the __getreent lib function for Cygwin to return the correct _reent
pointer all the time. Rename inline function to __inline_getreent
and introduce a macro __getreent calling the inline function. Change
the lib function __getreent to call __inline_getreent on Cygwin.

POSIX requires that SSIZE_MAX have the same type as ssize_t, but
on 32-bit, we were defining it as a long even though ssize_t
resolves to an int. It also requires that SSIZE_MAX be usable
via preprocessor #if, so we can't cheat and use a cast.
If this were newlib, I'd have had to hack _intsup.h to probe the
qualities of size_t (via gcc's __SIZE_TYPE__), similar to how we
already probe the qualities of int8_t and friends, then cross our
fingers that ssize_t happens to have the same rank (most systems
do, but POSIX permits a system where they differ such as size_t
being long while ssize_t is int). Unfortunately gcc gives us
neither __SSIZE_TYPE__ nor __SSIZE_MAX__. On the other hand, our
limits.h is specific to cygwin, so we can just shortcut to the
correct results rather than being generic to all possible ABI.

Newlib defines defaults for internal types via <sys/_types.h> and uses

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.

On Linux and in Mingw-w64, fexcept_t is defined as type unsigned short.
There are packages in the wild which rely on the fact that fexcept_t is
an integral type. We're changing the internal handling to use the bits
just as in GLibc, so only the 6 lowest bits are used to reflect the hw
bits. We even change the header file guard to reflect GLibc for compatibility.

GLibc's header.

This patch adds the long double functions missing in newlib to Cygwin.
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 subdir.
(DLL_OFILES): Add $(MATH_OFILES).

* 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,

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:
