So, at this point I'm thinking of changing it back to having %{!ansi:
%{!std=*|std=gnu*:-DCLIB2}} -D__CLIB2 -D__CLIB2__ etc in the specs file.
Although this is not really the proper way to do it, it's the least painful
solution and does the job well.
Why is using the specs file so bad?
The part above (defining different versions of CLIB2 symbol depending on
-ansi, -std switches) does things that are the job of the the preprocessor
and that it knows about best. Doing it in the specs file is not really that
bad, but it's not as clean.
How are other people using several c libraries doing it?
I am not aware of situation like ours where the default CRT can be changed in
the specs file, but cygwin's -mno-cygwin option does something similar in the
specs file like the part above.
