/* Test for bogus diagnostics for dremf definition.  Although this
   definition is formally incorrect in ISO C, a GNU extension permits
   a prototype followed by unpromoted types in a function definition,
   so it should be permitted when the function is built in.  Bug
   16666.  Test with -pedantic, where the problem should still be
   diagnosed.  */
