I downloaded CVS gcc and rebuilt everything.  On my first attempt
`make bootstrap' failed:

/opt/local/src/gccobj/gcc/xgcc -B/opt/local/src/gccobj/gcc/ -B/usr/local/i686-pc-linux-gnu/bin/ -B/usr/local/i686-pc-linux-gnu/lib/ -isystem /usr/local/i686-pc-linux-gnu/include -DHAVE_CONFIG_H -I. -I../../../../gcc/libstdc++-v3/libmath -I.. -I../../../../gcc/libstdc++-v3/include -I../include -g -O2 -c ../../../../gcc/libstdc++-v3/libmath/c_logl.c  -fPIC -DPIC -o .libs/c_logl.o

So I commented out lines 27-30 of /usr/include/bits/mathdef.h (Is this
the right way?), which seems to have worked.

Thanks again for your help.
