I think I can answer that myself now: the preprocessor is needed
because most of the times the record definitions are in hrl files,
that are included in the module source. I don't see any other reasons,
are there any?
I missed that because including files and ifdef-ing sections of code
aren't problems for me and are useful, so I kind of automatically
assumed that a restricted preprocessor that performs these tasks will
still be available. The predefined macros should probably be handled
by the preprocessor too.
