Hi,

As discussed with Robert Collins, I propose this patch to make
the 'default' mutex type more explicit.

2002-12-05 Christophe Galerne <christophegalerne AT earthlink DOT net>

	* pthread.h (PTHREAD_MUTEX_DEFAULT):
	reorder PTHREAD_MUTEX_DEFAULT and PTHREAD_MUTEX_RECURSIVE so that
	PTHREAD_MUTEX_DEFAULT can be defined as PTHREAD_MUTEX_RECURSIVE.
	add a comment that PTHREAD_MUTEX_NORMAL is not yet implemented.
