There is no change if libtool is used.
Some run-time support libraries provided by GCC (e.g. libgomp) use
configure checks to detect certain features, e.g. availability of
thread-local storage. The configure script generates a test program and
tries to compile and link it. It should use target libraries and
startfiles of the build tree if available and not random ones from the
installation prefix for this procedure. The search directories
specified by -B are a bit special, see for_each_path() in gcc.c of the
GCC sources. First a search is performed on all search paths with the
multilib directory appended (if desired), then a second search is
performed on demand with the base directory only. For each multilib
there is a "newlib" subdirectory. This directory is specified by a -B
option for the support libraries. In order to find the newlib artifacts
(ctr0.o, libc.a, libg.a and libm.a) they must be located in a proper
multilib subdirectory withing the build directory.

__sinit initialises some common file descriptors as line buffered and
relies on the first users of such FDs to call __smakebuf_r. If
__smakebuf_r realises there's no space for a buffer (malloc returns
NULL), it makes them unbuffered. However, while setting the __SNBF
bit, it doesn't clear the __SLBF bit in the flags. Depending on the
order in which functions check buffering flags in the FD, sometime
they assume it's line buffered (e.g. __sfvwrite_r), trashing
application memory that's not really been allocated to them.
This patch solves the problem by clearing the unbuffered/line buffered
flag when setting the line buffered/unbuffered flag.

In the case of memcpy-armv7m.S being built for a big-endian multilib
(including armv7 without a specific profile), realignment code made
assumptions about the byte ordering being little-endian.

Ensure the Python Lex/Yacc (PLY) cache used by makedocbook is initialized
before it is used by parallelizable rules to make the DocBook XML, as it
appears that these can collide in cache generation, leading to errors.

Turn pthread_spinlock_t into a self-contained object. On uni-processor
configurations, interrupts are disabled in the lock/trylock operations
and the previous interrupt status is restored in the corresponding
unlock operations. On SMP configurations, a ticket lock is a acquired
and released in addition.

This implementation is simple and efficient. However, this test case of
the Linux Test Project would fail due to call of printf() and sleep()
during spin lock ownership:

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.

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

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.

_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 477463a2011ba81907a753df9ce7a71b6563db54.
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
long (l) and long long (x) differ.
