Or you could have a special directive in DJGPP.ENV that causes the
startup to read a named file in the same syntax as DJGPP.ENV.  For
example:

	[gcc]
	%%include %DJDIR%/gcc.env

However, I don't see how this feature makes updating older packages
much easier.  It only solves the problem of those who edit their
DJGPP.ENV and don't want those edits to be overwritten by a package
they unzip.  But I don't think it does anything to allow multiple
versions of the same package to co-exist peacefully on the same
machine.  That's why GNU have chosen to have the version part of the
path name.

You could, of course, say, e.g. this in DJGPP.ENV:

	[gcc]
	%%include %DJDIR%/%GCC-VERSION%/gcc.env

and then change the version with a flip of a single variable in the
environment.

I think the issue of the stub coded inside Binutils vs the one in
`stubify' should be resolved, before we can really claim that core
DJGPP and GCC/Binutils are independent of each other.  The fact that
the new Binutils can read the stub using an environment variable is a
step in the right direction, but I don't think we should expect too
many people to set up environment variables.
