that all being said, i really don't think it's a hard feature to implement....
like i said, just whenever there is an 1) evaluation in the conditional
directives or 2) #define is called, look for "eval", if there, evaluate the
expression, then substitute token.
the rest of the needs no tampering at all. libccp's implementation is great,
neatly divided. probably have to edit only half a dozen files, at most -- at
least from what i can tell from scanning the the code.
it'll just take me a long time to know how to work with setting all the flags,
attributes, and working with the structs, so it's hard for me to do by myself.
