When compiled with -ansi and -pedantic, the following source file
gets 4 warnings.  I believe that the intent of -pedantic was to
provide GCC with fully ANSI conformant behavior.  Therefore, I
believe that the following code should generate 4 ERRORS rather
than 4 WARNINGS when -ansi and -pedantic are used.

(Side note: future ANSI-C test suites may contain (pedantic)
tests such as the following.  If GCC cannot be made to handle
such tests in an ANSI-conformant way, then such suites will
(rightfully) claim that GCC is *not* ANSI conformant.)
