How do you get MSVC to work?  Do you use cccl?  Patched libtool?
Or do you mean: use use libtool only when not using MSVC?
(Peter Ekberg is currently working on improved support for this compiler
in Libtool.)

That's most likely because libtool will eat those options,
and not pass them on.

Hmm.  This might be a bug fixed in 1.5.12.

If at all possible, please update to 1.5.18.  In any case, please
send the complete output of the link line with --debug added:
| /bin/sh ../libtool --debug --tag=CXX --mode=link g++ -no-undefined ..

Please pack the output (bzip2, gzip).  Not sure I can help you then,
but more data is necessary.

Cheers,
Ralf
