Thanx, I was wondering if there was such a switch too, but it really was
not my problem. (You can write "cpp test.c > test.i" too, although you
don't get the definitions that GCC normally provides (DJGPP, __MSDOS__ and
so on).

My PROBLEM was that in the below file, if we add a line #include <stdio.h>
I did NOT want that line to be preprocessed. *only* #include "" statements
should be preprocessed, and all #defines and such left alone.
