Okido.  I'll try to spin a little patch tonight or tomorrow
morning.

Yep.  DJGPP (up until the to-be-released-some-time-in-the-future
2.04 release, which DOES support symlinks) has limited 'ln -s'
support.  It will create an executable stub that will try to run
the given program.

So if you run 'ln -s X foo', you get 'foo.exe' (not 'foo'), which,
if run, will try to run 'X.exe'.  So trying 'ln -s' is a bad idea
there - it will succeed, but won't have the desired result (cfr.
the check made by autoconf 2.50 to see if 'ln -s' works).

In any case, here the -p flag wouldn't even be required for cp, so
its portability isn't even an issue, I think.  Using cp, ln or cat
is all fine - it's just 'ln -s' that has problems.

Or you could duplicate autoconf's test for ln -s and decide based
on that, but that seems overkill for a simple bootstrap.
