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 \

This (and a some further bugs) seem to have been fixed and I just finished
my first successful bootstrap since a couple of days ago...

...so now it might be a good time for another `cvs update`. ;-)

I can confirm it works better for a sparc-sun-solaris2.5.1 box as
well, time to grab a new cvs tree everyone.  Ding dong those wicked
bugs are gone.
