[Bug c/37940] New: no error detected for semicolon in C function declaration

[janis at gcc dot gnu dot org]

The following code has an extra semi-colon at the end of the function prototype
declaring bad_func1:

  void bad_func1 (unsigned long long arg1, const char *arg2 ; );

  void bad_func2 ()
  {
    const char *foo = "foo";
    bad_func1 (0, foo);
  }

GCC 3.4 reports an error:

elm3b187% /home/janis/tools/gcc-3.4-anonsvn/bin/gcc -c bug.c
bug.c:1: error: parameter "arg1" has just a forward declaration
bug.c:1: error: parameter "arg2" has just a forward declaration

GCC 4.0 and later (including current mainline) accept the code with no error or
warning, even with -Wall, and generate code as if the prototype did not exist
rather than generating code as if the semicolon did not exist.
