[Bug c/33995] New: C89 warning on inline keyword when using -std=c99 or -std=gnu99

[gcc-erikd at mega-nerd dot com]

Consider following trivial C program:

    inline int func (int x) { return x + 3 ; }
    int main (void) { return func (2) ; }

Compiling with:

   gcc -std=c99 file.c -o prog

or

   gcc -std=gnu99 file.c -o prog

results in the warning message:

   warning: C99 inline functions are not supported; using GNU89
   warning: to disable this warning use -fgnu89-inline or the gnu_inline 
            function attribute

The message states that inline functions are not supported using GNU89, but I
am specifically using -std of c99 and gnu99 so therefore I believe there should
be no warning.
