Yes, `gcc -v´ said "Using built-in specs", although the
%DJDIR%/lib/specs file exists.

Yes, that solves the problem. The specs file should be moved from
%DJDIR%/lib to %DJDIR%/lib/gcc-lib/djgpp/2.80, so gcc can find it.
`gcc -v´ says "Reading specs from %DJDIR%/lib/gcc-lib/djgpp/2.80/specs",
__DJGPP_MINOR__ is defined again and `unzip´ compiles happily with the
standard msdos/makefile.dj2.

I guess this should be mentioned in the readme.djg file that comes with
gcc280b.zip. At present, the text suggests that the specs file should
still reside in the lib/ directory ("Here is now a possible line
from the spec file in your lib/ directory:").

A sample output without the specs file:

|R:\DJGPP\C>gcc -v hello.c -o hello.exe
|Using builtin specs.
|gcc version 2.8.0
| r:/djgpp/lib/gcc-lib/djgpp/2.80/cpp.exe -lang-c -v -undef -D__GNUC__=2 -D__GNUC
|_MINOR__=8 -Dunix -Di386 -DGO32 -DMSDOS -DDJGPP=2 -D__unix__ -D__i386__ -D__GO32
|__ -D__MSDOS__ -D__DJGPP__=2 -D__unix -D__i386 -D__GO32 -D__MSDOS -D__DJGPP=2 -A

| hello.c g:/tmp/ccaaaaaa.i
[...]

And now with the specs file in the right place:

|R:\DJGPP\C>gcc -v hello.c -o hello.exe
|Reading specs from r:/djgpp/lib/gcc-lib/djgpp/2.80/specs
|gcc version 2.8.0
| r:/djgpp/lib/gcc-lib/djgpp/2.80/cpp.exe -lang-c -v -undef -D__GNUC__=2 -D__GNUC

|aa.i
|GNU CPP version 2.8.0 (80386, BSD syntax)
[...]

I don't know what the `-Asystem(unix)´ and so forth in the built-in
specs mean -- gcc.info does not seem to have a reference for it. Is it
something to be concerned about?
