We've had this discussion before... my instinct is that we don't want
to do this. gcc is planning on fixing their ICEs correctly for 4.5
(http://gcc.gnu.org/ml/gcc-patches/2008-10/msg01061.html), and glibc
will have a fixed tgmath.h in the next release
Therefore, I think we want to just make this an error unconditionally.
