Hi,
make pdf on Ubuntu 16.04 fail with:
newlib/libc/libc.texinfo:9: Missing @endcsname inserted.
After a lot of fiddling the reason appears to be the combination of concept
and function index despite a lack of concept index entries. Arguably texinfo
should not error in that case but here we are, newlib will fail to build its
documentation on some systems because of this. Since libc.texinfo only
contains function index entries this patch simply removes the combination of
indices. It does the same for libm.texinfo which has concept index entries but
no function index entries.
Tested by running make pdf, make dvi, make info and make html successfully.
libc.pdf appears to have only one index as expected.
== Proposed commit message ==
Fix pdf build failure with texinfo 6.1.0 as provided in Ubuntu 16.04. Index
combination in libc.texinfo and libm.texinfo fails because both file have only
one type of index entries. Removing index combination is thus harmless and
solves the problem.
Is this ok for master?
Best regards,
Thomas

_ctype_b is defined in ctype_.c as a const char array for non cygwin
targets allowing negative ctype index but as a char array for the same
targets in ctype_.h, giving type conflict at compile time. This is
because the cygwin targets are not treated specially in the latter file.
This patch adds the necessary logic for cygwin targets in ctype_.h.
While both long and long long are 64-bits on x86_64, they are distinct types,
and long was used prior to commit 477463a201.
Changing this breaks the linking of previously compiled C++ functions with
off_t arguments on 64-bit Cygwin with newly compiled code, as the mangling of

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

Add a simple rawmemchr implementation. Use strlen for rawmemchr(s, '\0') as it is the
fastest way to search for '\0', and use memchr with an infinite size for other cases.
This is 3x faster for large sizes.

The following testcase:
$ cat > test.c <<EOF

$ gcc -c test.c

e ‘_fpos64_t’
_fpos64_t _EXFNPTR(_seek64, (struct _reent *, _PTR, _fpos64_t, int));
^
The reason is that the load order from sys/select.h includes sys/_types.h
before sys/config.h has been included from anywhere else. sys/_types.h
defines _fpos64_t only if __LARGE64_FILES is defined, but it never is in
this scenario. So sys/_types.h has to make sure to get the configuration

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.

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_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.

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.
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.

__builtin_isinf_sign doesn't reflect the correct return value for NaN
to emulate finite function. Use __builtin_isfinite instead whichg is available
since GCC 4.4 just as __builtin_isinf_sign.
* libm/common/sl_finite.c (finitel): Use __builtin_isfinite.

Infinity returned from strtold is recognized as NaN by GCC builtin
functions. The reason is that ULtox is missing to set a bit.
* libc/stdlib/strtorx.c (ULtox): Set high bit in second word
to create valid Infinity value.

u_char, u_short, u_int, u_long are BSD-only types. Remove them from
Cygwin headers which are supposed to be used in a non-BSD scenario.
Drop special Cygwin handling of those types in sys/types.h.
newlib:
* libc/include/sys/types.h (u_char,u_short,u_int,u_long): Drop
Cygwin exception.
cygwin:
* fhandler_socket.cc (fhandler_socket::ioctl): Accommodate change
in include/asm/socket.h. Continue using u_long since that's the
MS type here.
* include/asm/socket.h: Since the type given in _IOR/_IOW macros
is only used for its sizeof, replace u_long with equivalent long.
* netdb.h (getnetbyaddr): Fix prototype.
* netinet/ip.h: Replace old BSD-only types with generically defined
old BSD types (u_char -> u_int8_t, etc).
* netinet/tcp.h: Ditto.
* netinet/udp.h: Ditto.

The u_intN_t types are BSD types but sanctioned by POSIX. They are
always defined when using Glibc headers so we follow suit.
newlib:
* libc/include/sys/types.h: Drop outdated __INTTYPES_DEFINED__
macro. Always define u_intN_t types.
cygwin:
* include/cygwin/types.h: Remove definition of u_intN_t types.

* libc/locale/ldpart.c (split_lines): Don't dereference result
of strchr without checking for NULL pointer first.

While C++11 was the first version of the standard to use C99 functionality,
TR1 (for C++03) also does, and G++ does not distinguish between C++98 and
C++03, or when TR1 is in use. Therefore, while not strictly correct for
"pure" C++98, enabling C99 for all C++ usage is the simplest solution (and
much better than always using -D_GNU_SOURCE as on Linux).

_LARGEFILE_SOURCE, which controls only these two functions, is implicitly
defined by _XOPEN_SOURCE >= 500. However, they are also later added to
POSIX.1-2001 (and therefore available by default).

When running RTEMS paravirtualized in user space, the cli/sti instructions
can't be used. But I can't see why they are needed in either user or
supervisor state. Turning the use of them off for RTEMS.
This code is unmodified since the beginning of the repository, so I have
no insight into why it was done. I may even have been the one to add them.
Absolutely no idea except they aren't necessary.
GCC 6.0+ asserts that the memptr argument to the builtin function
posix_memalign is nonnull.
Add the necessary annotation to the prototype and
remove the now unnecessary check to fix a warning.
