I think that libtool hasn't been told that LDFLAGS should include 
-L/usr/lib/w32api.  I think this is something that should be passed on 
the invocation line in your makefile -- maybe AM_LDFLAGS needs to be set?

No, it's not a file type or identification problem; libtool can't find 
libwinmm.a at all.

FWIW:

$ ./func_win32_libid.sh /usr/lib/w32api/libwinmm.a
x86 archive import

So that's ok.  (func_win32_libid.sh is just func_win32_libid() from 
libtool-2.2.2-2, with the OBJDUMP/NM/etc variables set.
