Thread Compilation Errors on Solaris

["Dan Schenck" <schenck istore com>]

I am trying to compile glib-1.2.9 on Solaris 5.8 using gcc version 2.95.2.  I am getting errors
compiling gthread.c.  Errors are as follows:

gthread-solaris.c: In function `g_mutex_new_solaris_impl':
gthread-solaris.c:52: `mutex_t' undeclared (first use in this function)
gthread-solaris.c:52: (Each undeclared identifier is reported only once
gthread-solaris.c:52: for each function it appears in.)
gthread-solaris.c:52: parse error before `)'
gthread-solaris.c:53: warning: implicit declaration of function `mutex_init'
gthread-solaris.c:53: parse error before `)'
gthread-solaris.c: In function `g_mutex_free_solaris_impl':
gthread-solaris.c:60: warning: implicit declaration of function `mutex_destroy'
gthread-solaris.c:60: `mutex_t' undeclared (first use in this function)
gthread-solaris.c:60: parse error before `)'
.
.
.

The files thread.h and pthread.h are in /usr/include.  I notice that mutex_t is defined in
/usr/include/synch.h.  I included this file in gthread-solaris.c but still get the following errors:

In file included from gthread.c:42:

Should I be configuring for the use of POSIX threads or is there some other problem?
