Hello Francesco,

thanks for the nice bug report.

IIUC this is a bug in dlltool, and exposed by using libtool because that
invokes dlltool, right?  Has there been any analysis of the nature of
the dlltool bug?  We should get that reported to the binutils developers
so it can be fixed upstream.

Unfortunately, I'm not really in the position to do this analysis myself
(both due to time constraints and lack of w32 experience), so I'll have
to defer to my more proficient w32 fellows here.
