RE: Windows DLLs from Unix with minimum effort

[Duft Markus]

Hi!

You might want to take a look at parity (http://www.sf.net/projects/parity). 
This has been written exactly - and only - for the purpose of compiling native 
windows programs from a UNIX-style environmet (currently only Interix is fully 
supported).

It also comes with a libtool patch, which makes it play together fine (all 
tests passed). Together with libtool i'm currently building about 6GB of object 
files a day on windows ;o) - and all is shared libraries!

If you've got any questions, just ask!

P.S.: @libtoolers(ralf): could you have a look at the patch, if maybe this one 
could make it into libtool? ;o) I've attached it. Maybe there are some tweaks 
to-do...

Cheers, Markus
