PATCH: gthr-dce.h update for trunk


This patch is for the trunk.  It updates gthr-dce.h to be functionally
equivalent to the version provided in the 3.0 release.  It defines
__GTHREAD_MUTEX_INIT_FUNCTION and __GTHREAD_MUTEX_INIT_DEFAULT.  These
are needed for threads with v3.

Checked with a complete bootstrap and check under hppa1.1-hp-hpux10.20:
<http://gcc.gnu.org/ml/gcc-testresults/2001-06/msg00423.html>.

OK?

Dave

	* gthr-dce.h (__GTHREAD_MUTEX_INIT_FUNCTION and
	__GTHREAD_MUTEX_INIT_DEFAULT): New macros for mutex initialization.
	(__gthread_key_delete): Remove code for __PTHREAD_LIBRARY_VERSION_1 >= 1
	(__gthread_mutex_init_function): New function for mutex initialization.
