No, same error. Good Question! I was stupid to not tested myself.

No, I tried, but I seems to have difficulties to compile it:
-I../../gcc/gcc/ada ../../gcc/gcc/ada/gnat1drv.adb -o ada/gnat1drv.o
gnatbind -C -I- -I. -Iada -I../../gcc/gcc/ada -o ada/b_gnat1.c -n
ada/gnat1drv.ali
fatal error: file gnat1drv.ali is incorrectly formatted
make sure you are using consistent versions of gcc/gnatbind

I can try again with other configuration options if you like.

Yes!

I'm compiling gcc again with -march=i686 instead of pentium4
