[cfe-commits] [Patch][Review request] Suppress warning about empty macro parameters in C++0x

[Jonathan Sauer]

Hello,

according to N3290 16.3p11, empty macro parameters are allowed (by not being disallowed anymore, as they
were in C++98 (and most likely 03; unfortunately I don't have access to the 03 standard)). Nevertheless,
when using "-pedantic", clang warns about empty macro parameters: "Empty macro arguments were standardized
in C99".

The attached patch fixes this by suppressing the warning not only in C99 mode, but also in C++0x mode
(diff from inside the directory tools/clang).
