There's an open DR 456 about this issue, with some discussion in
PR 6257 (suspended presently).

In general, when I want tight conformance (personally, always),
I pass "-ansi -pedantic-errors" to the compile flags. You can also
fine-tune with -std=c++{98,03,0x}. May not be bullet-proof, but
any issues can always be filed (and hopefully fixed). :)
Note also that strict standards conformance requires cooperation
with the operating system header files. This cooperation may come
in the form of additional -D command-line switches.
