I have a vague deja vu feeling here.  Which libtool version are you
using?  Which of the libraries are static, import libraries, or shared?
(Is this on Debian, with the libwinmm from the mingw32-runtime package?
That one is an import library)

I may have forgotten to finish/apply some fix here; need to go check...

Cheers,
Ralf
