Keywords: compiler C differences


We've all seen sources posted to the net when a comment such as "ported to
the PC using the Acme C compiler".  (Substitute your favorite compiler for
Acme :-).)  Since I only have experience with Microsoft C, my question is
"how different are these various implementations of C?"

What I would like to have is a compilation of the differences between
compilers X and Y which encompasses the more common C compilers for the PC.
In this group would be Microsoft C, Lattice C, DeSmet C, etc.  Please don't
flame at me if your favorite isn't named specifically.  If those of you on
the net who have knowledge of the differences between two compilers will
document and mail me the information, I will attempt to prepare a summary
and post it to the net.  In general, I think the things that would be of
interest are: differences in names of library functions that perform
identical tasks, presence/absence of common/useful functions in a particular
compiler (e.g., string functions, etc.), differences in calling arguments
or return values/types, and differences in capabilites of functions (e.g.,
signal trapping).  Please don't be limited by these examples, however.

Please feel free to send whatever you have.  I would rather be deludged 
with responses than to have everyone say "Somebody else has probably 
already sent this".  Note that if you don't see my summary in the next 
couple of months, then I probably didn't get any or many responses.
