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.
