Excellent sleuthing from Max, as always. Thanks!

Fair enough. And as the person who urged that libgcc be linked into
all shared libraries, I'll take the blame for this one. It was the
classic fix-a-bug-and-create-a-new-bug syndrome. The reason for the
addition of libgcc was to fix a backward-compatibility bug introduced
when we made exceptions work right. And the reason we rammed the
exceptions fix into 4.2 was because a bunch of folks (including
*cough* you, Max, if I remember correctly) told us in no uncertain
terms that we just HAD to fix that before 4.2 was released. It's hard
to know how to resolve that kind of conflict without simply slipping
the release date -- which was not an option, according to Jordan.
