From: Joel Sherrill <joel.sherrill@OARcorp.com>
Date: Fri, 1 Dec 2000 18:57:36 +0000
Subject: 2000-12-01	Joel Sherrill <joel@OARcorp.com>

	* Added macro support to POSIX API.  This is known to compile.
	* macros/rtems/posix/cond.inl, macros/rtems/posix/intr.inl,
	macros/rtems/posix/key.inl, macros/rtems/posix/mqueue.inl,
	macros/rtems/posix/mutex.inl, macros/rtems/posix/priority.inl,
	macros/rtems/posix/pthread.inl, macros/rtems/posix/semaphore.inl,
	macros/rtems/posix/timer.inl: New files.
	* configure.in: Removed error check for enabling macros.
	* rtems/posix/mutex.h: #if 0'ed out prototypes for inlined routines
	since you cannot have prototypes for macros.
	* macros/rtems/posix/Makefile.am: Added files.
