I agree with this in principle, but won't this break every single add-on module out there that supports Win32? -- Magnus HaganderMe: http://www.hagander.net/Work: http://www.redpill-linpro.com/

The patch didn't touch the contrib modules, so why would it break
third-party sources?

Oh, d'oh. I was clearly too tired when reading that thing. I was thinking we required changes in the contrib modules/third party modules, but they don't actually use DLLEXPORT, do they? In that case, that argument clearly falls, and I'm in favour of the patch :-) Just make sure you test it on both current and semi-old versions of mingw, they tend to not always act the same way. Or just get it in and the buildfarm can figure that part out for us. -- Magnus HaganderMe: http://www.hagander.net/Work: http://www.redpill-linpro.com/
