Update: I've reproduced this problem on 2.063.2, but while trying to
track down the problem, I discovered that building 2.063.2 from source
doesn't produce a working toolchain. :-( I've spent an hour trying to
figure out what's wrong with 2.063.2, but with no success. So, you
*could* be right that something may be wrong with libphobos2.a.

I'll try to download the tarball from dlang.org again and see if that
helps, or if I've messed up my system somehow. :-P
