If the preprocessor really does such extended work, can't one simply keep the intermediate output of the preprocessor as a source file and then relate to that?

I did quite some work in transposing C header files to Pascal. Most of the defines could simply be converted into const statements by h2pas.

For more elaborate stuff, like versions of installed C libs and such, the usual tools known C programming (m4, configure, …) can be used (Ultrastar Deluxe has quite some use of them), as already mentioned by Michael Van Canneyt. Due to their complexity, I would avoid them as much as possible.

My 2 cents - MiSchi.
