Note the ':)' This was just point that it's very hard to write software that
does not include *some* degree of platform-preference.

Anyway (going slightly OT here) regarding the '\', I think the one system in
wide use that insists on '\' would be Symbian. Porting Unix stuff is usually
not too hard with the Symbian's compatiblity-libc. (But maybe the
dir-separator is still the least of your concerns).

Ah, thanks. Solaris 10 is fairly important indeed.  Another one is Cygwin (it
added it fairly recently), Linux before 2.6.4. I've added a configure check
for now. Performance must be quite terrible with a working d_type.

Best wishes,
Dirk.
