# 'RTEMS_VERSION_LATER_THAN(major,minor,revision)'
#
# and
#
# 'RTEMS_VERSION_ATLEAST(major,minor,revision)'

# in config.h so applications can test for a particular

# Note that sometimes (mostly during x.y.99 pre-release
# phases) such changes happen w/o an associated change in
# revision number ;-(.
