In a quick dirty test (just deleting the gnu\build.gcc and gnu\gcc-3.2
directories) changing the case statement in gnu\gcc-3.2\gcc\config.gcc to
target seems to fix the issue with the target_alias being set to djgpp in
the file gnu\build.gcc\gcc\Makefile.  Here is a patch, although not fully
understanding the gcc cross compiler build process this might break
something else.
