[cfe-commits] [patch] Elided __VA_ARGS__ now erase preceding comma in MS mode

[Martin Vejnár]

I've beed asked to post this patch to cfe-commits, so there you go. The preprocessor show now consume a comma before elided __VA_ARGS__ even if there is no pasting operator in between. E.g.

    #define X1(b, ...) {b,__VA_ARGS__}
   X1(foo)

resolves to

    {foo}
