Re: GNAT parameter passing, C-style?

[Marin David Condic <nobody@noplace.com>]

This was my original point. AFAIK, there is no *requirement* that the 
parameters be put on a stack in any particular order - or even that 
there must be a "stack". A given machine might scrawl its parameters on 
a piece of paper with a pen plotter in Chinese characters from bottom to 
top and read them back in via scanner & OCR program reading right to 
left. So long as the parameters end up in the subroutine, the *standard* 
doesn't care how they got there. Hence no reason to believe there is a 
"C Method" or a "Pascal Method" of passing parameters.

We need to remember this or we muddy the waters when discussing what is 
required for Ada vs any other language.
