Mark Mitchell has just fixed this bug. An additional comment, just for
completeness: It would have been the -pedantic flag that should have
caused rejection.

-ansi selects the conformant behaviour if the code has both a GNU and
an ISO semantics. -pedantic makes gcc diagnose ill-formed code that is
accepted under a GNU extension.
