 *  ABSTRACT:
 *
 *	Header file for the CMA implementation of POSIX sigwait routine
 *
 *  AUTHORS:
 *
 *	Paul Curtin
 *
 *  CREATION DATE:
 *
 *	10 December 1990
 *
 *  MODIFICATION HISTORY:
 *
 *	001	Dave Butenhof	5 February 1991
 *		To avoid breaking client code (now that this is pulled in
 *		transparently by cma.h, pthread.h, pthread_exc.h), drop all
 *		the header file includes; which means also dropping the
 *		prototypes (oh well).
 *	002	Paul Curtin	9 May 1991
 *		Removed empty proto for cma_sigwait, should acquire from
 *		system header (ie, we redefine system sigwait to cma_sigwait)
 *	003	Paul Curtin	14 May 1991 
 *		Added full proto for cma_sigwait, not part of some systems...
 *	004	Dave Butenhof	19 September 1991
 *		Integrate HPUX CMA5 reverse drop; don't define cma_sigwait()
 *		wrapper if system supports _POSIX_REENTRANT_FUNCTIONS.
 *	005	Dave Butenhof	19 November 1991
 *		Remove direct check for _POSIX_REENTRANT_FUNCTIONS; rely on
 *		_CMA_REENTRANT_CLIB_, since we control that. OSF/1 defines
 *		_POSIX_REENTRANT_FUNCTIONS, but OSF DCE reference port isn't
 *		using libc_r.a. Preserve the intent (I hope) of HP's changes
 *		via checks for HPPA hardware.
