This appears to be working by design.

The duplicate specifier is allowed in C99 as well as C++11 (unless it appears
as a type specifier).  This is declaring a type specifier, so the only time the
warning should not appear is when compiling as C99 or above.

So if you specify -std=c89 along with -pedantic, or compile as C++ (including
C++11) along with -pedantic, you will see the warning.  But if you specify
-std=c99 and -pedantic, you will not see the warning.
