Hello!
Recently, there was a couple of patches posted on gcc-patches that
should fix various problems with solaris #includes. I would like to
point out, that there is similar problem on x86_64 with libc-2.3.5
(Fedora Core 4)

The problem causes a couple of warnings in gcc build, like this:

../../gcc-svn/trunk/gcc/unwind-dw2-fde.c:53: warning: (near
initialization for ‘object_mutex.__data.__count’)
I have produced a short testcase, where the problem can be shown:
--cut here--
#include <pthread.h>
static pthread_mutex_t object_mutex = PTHREAD_MUTEX_INITIALIZER;
--cut here--
Compiling this with 'gcc -W' produces:
thread.c:3: warning: missing initializer
thread.c:3: warning: (near initialization for ‘object_mutex.__data.__count’)
I'm not familiar with fixincludes, but perhaps somebody will be
interested in this problem.
Uros.
