MFC r350739-r350740 (by cem)
r350739:
Disable useless -Wformat-zero-length
It is part of -Wformat, which is enabled by -Wall. Empty format strings are
well defined and it is perfectly reasonable to expect them in a formatting
interface.
r350740:
r350739 try #2
For some inexplicable reason, C++ compilers reject the -Wno- flag, and also
(ab)use CWARNFLAGS.
