The non-standard pthread_yield() function is available at least on
Cygwin, FreeBSD and glibc.

This makes it possible provide operating system specific types for
<pthread.h>. It is in line with the FreeBSD header file structure and
allows a future cleanup of <pthread.h> to not expose unrelated things
via <sys/types.h> and <unistd.h>. Glibc uses the similar
<bits/pthreadtypes.h> for this purpose.

Add _TICKET_LOCK_INITIALIZER to statically initialize a

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
Provide __intmax_t and __uintmax_t via <machine/_default_types.h> and
define intmax_t and uintmax_t in <sys/_stdint.h> for FreeBSD
compatibility.

The original test is broken. It tests for a NULL locale which
isn't just wrong, it simply can't occur at this point due to an
earlier check for a NULL locale string. Thus, the locale info
for a category is never taken from the environment.

Update the getconf utility to support the new flag as well as
_PC_POSIX_PERMISSIONS and _PC_POSIX_SECURITY. These were previously
unsupported, probably as an oversight.

Additionally to eccefd97, we need to ensure the exception handler is
installed for the _ljfault used to implement _try/_except to get called.
Also use the correct macro for x86 conditional compilation.

Long-standing problem in one of the corner cases of rename(2):
If we rename a directory a check is performed to see if newpath is
identical to oldpath or a subdir of oldpath. This check is
(accidentally? no hints anywhere in ChangeLogs or code) performed
case-insensitive for as long as we use Unicode paths and NT functions.
This leads to the problems described in
https://cygwin.com/ml/cygwin/2016-09/msg00264.html
Change this to be conditional case-sensitive as all other checks but
let's take this with a grain of salt. There may be corner-cases in
this corner-case which require to chek parts of the path always
case-insensitive. Off the top of my head I can't construct such a
case but that's no proof they don't exist :}

Commit d16a5630 dropped usage of cygheap's locale functions
in favor of local on-the-fly usage of UTF-8 instead of ASCII.
This allowed to use the current local rather than a fixed
system-wide locale set at startup time. d16a5630 just missed
to add the ASCII->UTF-8 conversion in the console as well.

_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.

Yep.

No problem - attached.
This renders the original patch 4/4 valid again.

executable is in "x/bin/", search for "x/bin/N" before "x/lib/N".
