I believe this correlates to IE rather than Windows.  If I remember 
correctly, IE v4 or greater is necessary.  We already make assumptions
in some places that at least IE v5 is installed so I don't think adding
more code with a similar assumption is a problem.

I remember talk of this ages ago but I don't remember details.  Should be
possible for C code.  You'd have to google for more info. ;-)


>3. And whether gcc would produce a compatible binary?


As long as they are "C" callable.  It's probably also preferable to use the
-mno-cygwin switch in this case as well.

Ah, now that's the *real* question! ;-)  It would be "cool" and "useful"
but I expect there isn't an objective way to measure whether it is worth the
effort.
