Since when does gcc 3.2 support -fbounded-pointers (aside from accepting the
option)? AFAIK it was only on bounded-pointers-branch in gcc CVS, last
updated around January 2001. If you want --enable-bounded, you need to use
that compiler (but, glibc 2.2.91+ is compilable by gcc 3.2+ only, so unless
somebody revives the bounded-pointers project, you shouldn't use
--enable-bounded at all).
I don't think it makes any sense to put any effort into glibc part of bp
until gcc part gets back from its zombie state.
