I'm sorting through C code loaded with #ifdef statements for portability. I'd
like to strip the code down to a version that applies to my operating system
and configuration so that I can read through it but don't want to preprocess
all the #define statements, as I'd like to see the #define mnemonics in the
stripped down code. I don't see any options for the C preprocessor that will
allow me to preprocess #ifdef's but not #define's. Is there an easy way to do
this?

You can define whatever you want, and all the undefined "#ifdef"s will look something like: #ifdef FOOBAR ... #else printf("I am not a foobar\n"); #endif -- Bruce Dumes | "You don't see many of *these* nowdays, | bad@zen.cac.stratus.com | do you?" |
