have -Wno-* work the same on gcc3 as well.
old patch, belated test by aoyama@, okay aoyama@

Port the gcc2 bounds checking support to gcc3, activated with -Wbounded
and documented in gcc-local(1).

tested by marc@ brad@ and lots of bulk ports builds

Import gcc-3.3.2. Only the compiler. ada frontend removed for space
considerations.
