Of course, a proper implementation of close() will just ignore an
invalid parameter silently, and set errno. But apparently the "debug"
version of the Microsoft C library generates some noise in this
case. So avoid that. Thanks to John Emmas for reporting.
These allow applications to give meaningful names to their sources.
Source names can then be used for debugging and profiling, for
example with systemtap or gdb.

For some reason, even though the tests are linked against libgobject.la
and libgobject.la mentions libglib.la as a dependency, the tests are
running against the system glib instead of the in-tree one.
Adding the libglib.la file as an explicit LDFLAG fixes it.
Re-using glibc's __abort_msg symbol causes linking problems, since the symbol
is declared private. Always use our own__glib_abort_msg symbol to store
assertion messages, to avoid compatibility and linking problems.
Also fix the test case to work with out of tree builds (such as "make
distcheck"), and re-enable it.

It makes the IBM XL C Compiler (the 'native' non-free compiler
on the AIX 5.3 and 6.1 platform) stop compiling with syntax error.

Crash interception/debugging systems like Apport or ABRT capture core dumps for
later crash analysis. However, if a program exits with an assertion failure,
the core dump is not useful since the assertion message is only printed to
stderr.
glibc recently got a patch which stores the message of assert() into the
__abort_msg global variable.
(http://sourceware.org/git/?p=glibc.git;a=commitdiff;h=48dcd0ba)
That works fine for programs which actually use the standard C assert() macro.
This patch adds the same functionality for glib's assertion tests. If we are
building against a glibc which already has __abort_msg (2.11 and later, or
backported above git commit), use that, otherwise put it into our own field
__glib_assert_msg.
Usage:
$ cat test.c
#include <glib.h>
int main() {
g_assert(1 < 0);
return 0;
}
$ ./test
**ERROR:test.c:5:main: assertion failed: (1 < 0)
Aborted (Core dumped)
$ gdb --batch --ex 'print (char*) __abort_msg' ./test core
[...]
$1 = 0x93bf028 "ERROR:test.c:5:main: assertion failed: (1 < 0)"
