I fixed this about a week ago (unless its a new problem).

This sounds similar to the PR java/2095 reported on Solaris. It probably
affects multiple platforms (maybe just SJLJ ones?). It probably doesn't affect
the branch.

Good question. This has been happening since around about when we changed to
the shared libgcc. Maybe the compiler just needs to add an implicit "-u fwrite"
when static linking? I don't know why c++ works and gcj doesn't though.
