Here is where you are absolutely wrong.  It "should work"
but it *does not work* without bison.

I just downloaded gcc-3.2.1.tar.gz, and proceeded to do a bootstrap and it failed:

=============================================================================
make CC="gcc" libdir=/home/rodrigc/release/gcctest/lib LANGUAGES="c"  CFLAGS="-g
" MAKEINFO="makeinfo"  MAKEINFOFLAGS=""
(cd intl && make all)

ural.y
rm -f plural.h

rodrigc/release/gcctest/lib\" -DHAVE_CONFIG_H -I.. -I. -I../../../gcc-3.2.1/gcc/

ototypes -Wtraditional -pedantic -Wno-long-long  plural.c -o plural.o
gcc: plural.c: No such file or directory
gcc: No input files specified
*** Error code 1
===============================================================================

build/gcc/intl/Makefile expanded the YACC variable to:

YACC = : -y -d


So, the bootstrap *does not* work without bison.

I still think my configure patch should go in.
If someone wants to fix all the *.in files so that they work without
bison, then my patch will be unnecessary, but the way things
are now, it looks like that is not the case.
