Jason, would it be possible for you to try changing the .ico file, along
the lines described by David, so that the MS compiler is happy with it?
Normally we should not go out of our way to accomodate MS Visual studio,
but this seems to be a moderately easy fix.

If you can't fix this and/or would prefer to drop support for MSVS
instead, could you please update nt/INSTALL and etc/PROBLEMS with the
information in this bug report?  Thanks.
