 GCC's command line options are case sensitive.  The option you are
 trying to use is spelled -ansi; however, we encourage the use of the
 -std option instead (-std=c89 for the 1989 C standard, -std=c99 for
 the 1999 revision).
 
 -ANSI is interpreted as a use of the -A option with an invalid
 argument. "missing '(' after predicate" is a correct, although
 unhelpful, error message.
 
 Red Hat's 2.96 crashes because of a bug that was fixed a long time ago
 in the official source tree.  GCC 3.0 (as you saw from the online test
 compilation form) will not crash.  2.95.x also does not crash.  You
 should report this crash to Red Hat; we cannot fix bugs in their
 version of the compiler.
