Eli,

This recipe worked perfectly; some comments and questions are below.
Thanks!

-: 
-: Try this:
-: 
-:   - Rename the old gcc.exe to gcc2721.exe.
-: 
-:   - Create a directory lib/gcc-lib/djgpp/2.721/ and move the old
-:     cpp.exe, cc1.exe, and cc1plus.exe from bin to this new directory.

And the old bin/gxx.exe that comes with gcc2721b.zip ?


-:     Move the old lib/libgcc.a and lib/specs to that directory as well.

Using lib/specs taken from djdev2.02 and updated to 2.03.


-:   - Rename the old lang/ directory to lang-2.721/.

If there is a lang/ directory (which there should be if lgp271b.zip
and/or obc2721b.zip was installed).


-:   - Edit djgpp.env and add a [gcc2721] section with this content:
-: 
-:     [gcc2721]
-:     COMPILER_PATH=%DJDIR%/lib/gcc-lib/djgpp/2.721
-:     LIBRARY_PATH=%/>;LIBRARY_PATH%%DJDIR%/lib/gcc-lib/djgpp/2.721;%DJDIR%/lib
-:     CPLUS_INCLUDE_PATH=%/>;CPLUS_INCLUDE_PATH%%DJDIR%/lang-2.721/cxx;%DJDIR%/include
-: 

As you indicated in another message, there should be *no* trailing slash
in the value COMPILER_PATH.


-: Thereafter, you should be able to invoke the old compiler as
-: "gcc2721".

Works like a charm.  Just to make sure everything worked, I relocated
gcc2721 and recompiled various packages *before* installing a newer GCC.

Just curious: could the 2.7.2.1 info/ directory be relocated as well,
with appropriate additions to djgpp.env?
