Too gross and risky, IMHO.

How about actually making %DJDIR%/lib/gcc-lib/2.81/lib be part of
LIBRARY_PATH in v2.02's DJGPP.ENV?  For example:

LIBRARY_PATH=%/>;LIBRARY_PATH%%DJDIR%/lib/gcc-lib/2.81/lib;%DJDIR%/lib;%DJDIR%/contrib/grx20/lib

If this works, then gcc 2.7.2 will just try to search a non-existent
directory and settle for %DJDIR%/lib, while gcc 2.8.1 will happily
find its own directory.

The only situation when this will need tweaking is for those who want
to have dual 2.7.2/2.8.1 installation.  But those will need to edit
DJGPP.ENV anyway.

Comments?
