Oh.  It seems that the stock gcc-2.7.2.1 doesn't understand the
-mtrap-precision and -mfp-trap-mode arguments.  The gcc patches from
http://www.freebsd.org/~dfr fix this.  Unfortunately I use these patches
all the time so I didn't notice that the unpatched compiler doesn't
support software completion properly.  I'll back out the Makefile change
in msun until we upgrade to a decent compiler.
