[Dan Nicolaescu]

On i686-pc-linux-gnu (RedHat-6.2)

configured with:

../gcc-CVS/configure  --prefix=/home/dann/GCC-newRA --disable-nls --disable-multilib --enable-languages=c --enable-checking=misc,tree,rtl,gc,gcac


when bootraping it gives (while building stage1):

./xgcc -B./ -B/home/dann/GCC-newRA/i686-pc-linux-gnu/bin/ -isystem /home/dann/GCC-newRA/i686-pc-linux-gnu/include -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -isystem ./include -I. -I. -I../../gcc-CVS/gcc -I../../gcc-CVS/gcc/. -I../../gcc-CVS/gcc/config -I../../gcc-CVS/gcc/../include -g0 -finhibit-size-directive -fno-inline-functions -fno-exceptions -fno-omit-frame-pointer -c ../../gcc-CVS/gcc/crtstuff.c -DCRT_BEGIN -o crtbegin.o
