I think we need to drop Win9x and WinNT4 for fltk-1.3 or later anyway; getting
the UTF8 stuff to work on them is tricky, as none of them really supported the
necessary functionality "out of the box" and it was (in some cases) patched on
as an afterthought... So there's no way to know whether any given version will
actually work or not.
IIRC, some of the additions were never available as service packs, but instead
kind of "sneaked in" as upgrades to IE or Word, so unless the user happens to
have the correct combination of service packs and other random packages... It
is not going to work.
Also, a lot of stuff in fltk-1.1 doesn't really fly on WinNT4 - all the
multi-head support stuff, for example; though I did try and make that optional
at runtime. We still had a few NT4 boxes when that code went in... All long
gone now of course. Oh, take that back - we still have an old PC running NT4
that serves FTP for some of our test sets... Not available for fltk testing
though!
Though I think I have a WinNT4 VM on a Mac somewhere...
