This is a patch for the installation of frameworks on
MinGW32 targets, which was badly broken.
This patch may still not do what everyone wants, but at
least it successfully installs the frameworks for now
without creaking. If someone can explain a few things to me
then I'd be happy to tweak it:
(1) for objc frameworks, do .a files need to be
created/installed as well as .dlls? (as for the main gnustep
libraries which have both).
(2) should we be striving to keep the dlls inside the
framework folders, or is this a lost cause on Windows, when
the dlls have to be in the PATH?
In any case I think this patch is a good start.
