The above line is needed because the original order of Sed commands
will remove the colon from DOS-style d:/foo/bar pathnames--a very
nasty bug indeed.

These support passing arguments to the configure script invoked by
config.bat.  Since you cannot pass foo=bar as a single argument to a
batch file on DOS (try it!), the above magic changes the configure
script so that : is used instead of =.  Now you can say e.g. this:

       djgpp\config --program-prefix:gnu

and get gnused.exe instead of sed.exe.
