Comment 1 Tom Tromey 2005-06-15 22:42:24 UTC 
I'm not sure that building a shared library with gcj on windows
is supported.  (But I'm not an expert on our windows port.)

Can you provide more information about this failure?
A stack trace might help.  Or if the jar is small and not proprietary,
it might help.  Or, perhaps a reduced test case.

Unfortunately this isn't enough information for us to do anything with.
