Oct-files work fine.

My patches are a little bit broken.  Given the rebuild time, it will be a
while yet before I've got them solid.

Only if you don't strip the DLL first.  But then you have a 12 Mb dll
instead of a 2.5 Mb dll in the case of liboctave.  Also, mkoctfile has
to link against the binary directory where the DLL's are installed rather
than the lib directory.  Are either of these a problem?
