Strange, I did diff against CVS head, copy of message returned to
me contains everything I put there. Unfortunately, there's no online
archive of libtool-patches (why?), so I can't look there.

Thanks! That's what I wanted first of all - shorten size of my
patches.

But how that influence DJGPP or other DOS ports of gcc? That
change applies only to win32 hosts (in fact, only to gnu-win32, I
intentionally left hyphen-delimited naming for non-gcc's). Only time
this may apply is when cross-compiling from djgpp to gun-win32 host.
Well, then:
- If it is done on one of win9x systems, LFN facility is used which
transparently proxies win32 naming to djgpp apps.
- For NT systems, there're separate package to achieve that.
- Only when one does that on bare dos, that will be problem. But I
guess it's fair to suggest in such case to take care that djgpp
convert filenames to representation acceptable by underlying layer.
(And IMHO, this might be done in official djgpp - well, maybe it's
even done already, I'm looking at 2.01 _put_path()).

But my original patch (hm, below) would allow to save sensibility
for something more useful. Don't provide excess configurability when
it's hardly needed. (Automake won't generate that option specially for
gnu-win32, will it? And when I would like DLL name to differ from
standard, I can simply rename it after building.) YMMV
