function call. On such systems, define this to a
function which looks like this:

Don't define __GTHREAD_MUTEX_INIT in this case

All functions returning int should return zero on success or the error
number. If the operation is not supported, -1 is returned.
Currently supported threads packages are
- POSIX threads with -D_PTHREADS
+ TPF threads with -D__tpf__
+ POSIX/Unix98 threads with -D_PTHREADS
+ POSIX/Unix95 threads with -D_PTHREADS95
DCE threads with -D_DCE_THREADS
Solaris/UI threads with -D_SOLARIS_THREADS
