Cygwin != Windows but Cygwin does run on Windows. Hence, we need a DLL, 
and, for Cygwin, we need a "special" prefix for the libs: "cyg" 
Also, the ON_WINDOWS and NOT_ON_WINDOWS makes it behave properly on MinGW, 
which is part of what I wanted

The Cygwin/Windows part doesn't use Libtool for a reason: DLLs don't get 
created properly with the current libtool (as you have apparently found 
out in another mail).

Also: this ON_WINDOWS stuff is just a generalized version of the patch 
Corinna has developed for PCRE - the only difference being that it also 
works for MinGW. I see no reason to change it, at least until DLL support 
in Libtool on Cygwin works properly.

That might be a good idea - I'll apply that part of your "patch"

That would probably mean that mr Hazel (the original author) will have to
relibtoolize, but I do agree with you on it - though there is no real
reason to do so except in preparing for the day Libtool works properly on
Cygwin..

Thanx :)

Don't know - I'd have to ask.

I have :)
