I would like to modify this to use a generic flag rather than a check 
for __rtems.  I really want to change all the various OS and platform 
checks we have in shared headers/code and replace them with more 
generic-usage ones (Cygwin and rtems are the most prevalent).

In this case, I would like to suggest either HAVE___ASSERT_FUNC or 
_EXTERNAL_ASSERT_FUNC (or feel free to come up with a better one).

I can make the change myself and add the flag to the rtems set in 
configure.host if you are ok with any particular flag choice.
