Or you could follow what we did for glibc, and stop having plural.c being 
checked in to either the GCC or binutils-gdb repository, and arrange for 
it to be generated in the build directory.  (With due care to ensure it 
gets into release tarballs, which for GCC means ensuring 
--enable-generated-files-in-srcdir causes it to go in the source 
directory, and that if you build from a release tarball that does have it 
in the source directory, the source directory copy gets used when you 
don't have Bison installed.)

For binutils and GDB, Bison is already a build requirement when building 
from version control.  GCC doesn't currently have any Bison parsers, so 
this would be restoring an old build requirement there.
