Boostrap failures on Solaris at gcc/toplev.c stage2 compilation

[Art Haas <ahaas at impactweather dot com>]

Hi.

This morning's build attempts on both i386-pc-solaris2.10 and
sparc-sun-solaris2.10 failed with the following error:

/export/home/arth/gnu/gcc-1124/./prev-gcc/xgcc -B/export/home/arth/gnu/gcc-1124/./prev-gcc/ -B/export/home/arth/local/i386-pc-solaris2.10/bin/ -B/export/home/arth/local/i386-pc-solaris2.10/bin/ -B/export/home/arth/local/i386-pc-solaris2.10/lib/ -isystem /export/home/arth/local/i386-pc-solaris2.10/include -isystem /export/home/arth/local/i386-pc-solaris2.10/sys-include    -c   -g -O2 -gtoggle -DIN_GCC   -W -Wall -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -Werror -Wold-style-definition -Wc++-compat   -DHAVE_CONFIG_H -I. -I. -I/home/ahaas/gnu/gcc.git/gcc -I/home/ahaas/gnu/gcc.git/gcc/. -I/home/ahaas/gnu/gcc.git/gcc/../include -I/home/ahaas/gnu/gcc.git/gcc/../libcpp/include -I/export/home/arth/local/include -I/export/home/arth/local/include  -I/home/ahaas/gnu/gcc.git/gcc/../libdecnumber -I/home/ahaas/gnu/gcc.git/gcc/../libdecnumber/dpd -I../libdecnumber    /!

/home/ahaas/gnu/gcc.git/gcc/toplev.c: In function 'crash_signal':
/home/ahaas/gnu/gcc.git/gcc/toplev.c:445:3: error: implicit declaration of function 'signal' [-Werror=implicit-function-declaration]
cc1: all warnings being treated as errors

The likely cause is this patch applied yesterday:

2010-11-23  Joseph Myers  <joseph@codesourcery.com>
        { ...snip ... }
        * toplev.c: Don't include <signal.h> or <sys/resource.h>.
        (setup_core_dumping, strip_off_ending, decode_d_option): Move to
        opts.c.

With the issues involving libquadmath I'm not expect the i386 build to
succeed even once this snag is resolved, but my sparc builds have been
working, and I had a successful build yesterday morning:
