Yes, but can I get the compiler to show me the code just after going
through the preprocessor?  I sometimes need to see this for debugging
purposes.

Example (this happened yesterday):  A bunch of symbols weren't being
defined, but the header file containing them was in the include path.
When I looked at the output of cpp, I noticed that the header file that
was included was in the current directory and not the one I was
expecting.  Without the output of cpp it would have taken me a heck of a
lot longer to find this problem.


I don't care if the preprocessing is integrated with the other phases of
lexical analysis, just as long as it is possible for me to get the output
from the preprocessor when I need it.  Will ANSI require that, or will it
be implementation-dependent??
