I unfortunately also don't have a good answer to the gcj support issue.

But this raises another bdwgc question: Is anyone actually still using the
OS2 code? I think the motivation for the current patch was that the code
fails cppcheck. Probably the best solution for such problems in general is
to remove support for dead platforms? Like Andrew, I don't recall seeing
any OS/2 use in quite a few years. According to Wikipedia, some ATMs may
still be running it, but I doubt we care.
