[fpc-pascal] FPC macros

It won't, it will be nice for your only particular case (save typing). See
point #2 of http://freepascal.org/faq.var#extensionselect

IMO the use of macro itself, in your case, is already an abuse. If it's only
to name '?mat.name', then a const is better. But I guess this is only to
shorten writing multiple parameters, which is not a good reason since it
compromises ease of reading (misguess the real number of parameters). FPC
preprocessor is not as sophisticated as C/C++ and it's designed as such to
disallow abuses. If you insist, please use external preprocessor instead.
