is it possible to change the format of __FILE__ + __DATE__,
for example instead of hh:mm:ss ss:mm:hh?
Not in (standard) C, but <OT> for make (and perhaps some other build
systems) on some systems you can do something like:
c89 -DMYDATE=`date +%blahbah` otherflagsandfiles
Filenames are somewhat harder in general because essentially all
nontrivial translation units will involve more than one source file.
Also on non-Unix systems there is variation in the preferred and even
allowed syntaxes of filenames/pathnames/etc. You may have to punt on
these issues, or at least limit your supported platforms.
But if what you want is some component and/or version identifier(s)
that are different from the standard ones, just make your own.
