[cfe-dev] Disable fms-extensions?

[Andrey Bokhanko via cfe-dev]

Hi Zahira,

-fms-extensions can obviously be disabled with -fno-ms-extensions. This
won't necessarily mirrors /Za exactly, though -- as according to MS, /Za
disables *all* C++ extensions, not only MS-specific ones. I doubt anyone
tried to implement a mode that mirrors /Za exactly.

Yours,
Andrey
