today's CVS version fails to build on i586-pc-linux-gnulibc1

[Joe Buck]

Finally got anonymous CVS going on my home Linux box
(i586-pc-linux-gnulibc1, Red Hat 4.2).

I get an internal compiler error when trying to build today's CVS
version, though.  tinfo.cc fails to build.  The output is

./xgcc -B./ -O2   -DIN_GCC   -DUSE_GNULIBC_1 -W -Wall -O2 -g -O2 \
-I./include  -fPIC -g1  -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -fexceptions \
-I. -I../../egcs/gcc -I../../egcs/gcc/config -c ../../egcs/gcc/cp/tinfo.cc
