In fact I already missed sadly a fully working preprocessor (to be activated optionally). This does help with Pascal sources from time to time (in fact I do like macros better than generics :) ).
You could use the scanner/preprocessor part of ToPas, if you want an fully conforming C preprocessor. I think that I dropped this project from ToPas, but it could be added again without problems. IIRC Skalogryz currently is porting all that stuff from Delphi to Lazarus...
I don't see why simply calling the gcc preprocessor is not a viable option (at least with Lazarus on Linux). Supposedly for a better integration a Pascal based workalike preprocessor might be better.
The C preprocessor most probably depends on C syntax (strings and other literals...), so its use may be restricted to such source code. AFAIR the C90 standard (C98 for sure) already required that the preprocessor is an integral part of the compiler, so that up-to-date stand-alone preprocessors may be rare. And not all of them comply to the standard, with regards to proper macro expansion. I know about two extreme cases, where the Sinix(?) preprocessor insisted in expanding #defined symbols even in string literals, and the Microsoft preprocessor has other incompatible ideas about macro expansion and comments; you'll find more details in the ToPas documentation...
