It was like that before v2.03.  However, the specs file is specific to
the GCC version, and GCC ports are released with no particular
connection to DJGPP releases, and at a much higher rate.  So v2.03
removed lib/specs from djdevNNN.zip, and we needed a way to have 
__DJGPP__ and __DJGPP_MINOR__ be still in synch with the library being 
used (without telling users to edit their specs files).

I don't know if this is a bug or not.  It seems like GCC is treating
-imacros as user header files.  Which is probably reasonable in some
situations, but not in this context.

If you can suggest a better way of solving this problem, please do.
At the time, this was discussed on the developers' list, but all other
solutions were met with opposition.
