Already fixed for GCC 5.
v.c:2:21: warning: ISO C++11 requires at least one argument for the "..." in a
variadic macro

No, the standard doesn't require an error, it requires a diagnostic message.
"If a program contains a violation of any diagnosable rule or an occurrence of
a construct described in this Standard as “conditionally-supported” when the
implementation does not support that construct, a conforming implementation
shall issue at least one diagnostic message."
A warning is a diagnostic message, ergo there is no bug.
As Andrew pointed out, use -pedantic-errors (or -Werror=pedantic) if you want
to turn such warnings into errors.
