I get undefined references at link time for everything linked against
libgcj because, for example, exception.o gets replaced later on by
something else named something/Exception.o, and so the important
exception symbols are not present.
Its possible that the case-insensitivity of the filesystem is causing
problems.
On the other hand, other people seem to be building libjava on
i686-pc-mingw32 with few problems, so I'm not sure what I'm doing wrong
here.
