Re: rendez-vous underlying mechanism

["Jeffrey Creem" <jeff@thecreems.com>]

cpp is the c-preprocessor..
cc1 is that C compiler "main"

You can delete both of them and still compile, link and run an Ada program.
(if you are going to "try this at home", please don't really delete them ;)


In any case, GNAT does not translate your code to C. I've spent more of my
free time than I care to admit looking at GNAT source code (for fun only).

Don't take my word for it. Take Rober Dewar's word. He knows a little bit
about the internals
of GNAT :)

I am sure I can find a few more references.. In any case, it is a popular
misconception probably
caused by the original Acronym and the old method of the binder producing a
single C file.
