[Bug c++/25152] [4.0 only] no warning from -Wstrict-aliasing for C++ code

["jakub at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #8 from jakub at gcc dot gnu dot org  2005-12-08 12:30 -------
-Wstrict-aliasing backport has been committed today to gcc-4_1-branch:
http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=108226

For 4.0, it is IMHO a bad idea to backport this, there are tons of programs
built with -Werror and if we suddenly start issuing a huge amount of new
warnings (and this warning has sometimes many false positives), we'd force
people to change packages a lot.  People are used to do this kind of things
when porting to a newer major GCC version, but e.g. when upgrading from
x.y.z to x.y.z+1 it is not expected.
