Image support has always worked for me with both gcc and msvc
(non-optimising version though). I recall we made some changes to
detect broken versions of some libraries and refuse to use them, but
was not aware (had forgotten?) that the problems were still there.

I think the problems with MSVC's optimisations is likely due to
alignment differences in structs we are passing into the library. If
the problem is just with MSVC, we can just add a note to PROBLEMS,
since the official binaries will be built with gcc anyway.

Remember anything we distribute in binary form, we also need to
distribute source for. Rather than clutter the gnu.org servers with
non-GNU image library code just because some Windows users might want
to recompile their Emacs with a proprietary compiler, I think we can
just say that such people should recompile the image libraries
themselves too. That is the easiest way to ensure that the image
libraries will work.


There may also be problems with specific versions of image libraries
that affect a gcc build of Emacs as well. These cases we should try
to find out why and test for it when loading the libraries.
