I'll try that, thanks.  I notice that the '.hidden' isn't in cvs yet.
I also notice you've been trying to get that into CVS for two years
now (http://gcc.gnu.org/ml/gcc-patches/2001-10/msg00053.html).
Time for another try?  It'd be nice if gcc-3.4 (and maybe even gcc-3.3.3)
didn't need a patch for this.
