gcc2.8.0 doesn't define __DJGPP_MINOR_ anymore. To get around this
problem for now, change the line defining "LOC" in makefile.dj2 like
this for the current DJGPP v2.01:

LOC=-DDOS -DUSE_VFAT -DUSE_UNSHRINK $(ASMFLG) $(LOCAL_UNZIP)
-D__DJGPP_MINOR__=01

(this is all one line!)

Good question. Will __DJGPP_MINOR__ be automatically defined in the next
gcc release or an intermediate update? Can we put a specs file somewhere
and define that value there? I seem to remember that gcc2.8.0 has a
built-in specs file, but I don't know how to create a completely new
one.

Or shouldn't we count on having __DJGPP_MINOR__ defined? After all it's
just used to print the DJGPP/gcc version number for `unzip -vī, not for
any "real" functions (at least not in unzip).
