* General effort to make things compile with macros not inlines
* inline/rtems/score/coremutex.inl: Added comment indicating
for macros there is another copy of
_CORE_mutex_Seize_interrupt_trylock() in src/coremutexseize.c.
* src/coremutexseize.c: Added body of
_CORE_mutex_Seize_interrupt_trylock() for macro case.
* macros/rtems/score/coremutex.inl: Added prototype for
_CORE_mutex_Seize_interrupt_trylock() since there is a real
body when macros are enabled.
* macros/rtems/score/coresem.inl: Added macro implementation of
_CORE_semaphore_Seize_isr_disable.
* macros/score/Makefile.am: Fixed typos.
* rtems/score/address.inl: Correct macro implementation of
_Addresses_Is_aligned() so it would compile.
* macros/rtems/score/coremsg.inl: Added closing parentheses.
