GCC Bugzilla Bug 10113

Confirmed with 3.2 CVS 20030309, 3.3 CVS 20030314, HEAD 20030302.

This is a regression from gcc-2.95 and isn't fixed by gcc-snapshot
(20030118-1).  Compiling without optimization (-O0) makes the ICE go
away.  I've made the -save-temps output available here:
  http://people.debian.org/~troup/fpu_ieee.ii.gz

(It's 280k uncompressed, so I haven't included in the report, sorry)
