Replicating xlc's __assert1 and __assert2 on AIX

[Perry Smith]

I want to replicate what IBM's xlc does for __assert1 and __assert2.   
These built in functions generate trap instructions.

I believe I can do this using "asm" statements but this is new  
territory for me.  Mostly, this note is to just make sure that I am  
not re-inventing the wheel.  If this has already been done or  
something equivalent, please let me know.  Or... if anyone has some  
free advise, that will surely save buckets of time.

Thank you,
Perry Smith
