["oder at eleks dot lviv dot ua" <gcc-bugzilla at gcc dot gnu dot org>]

Consider the following example

---- begin of test.c ----
int main(int argc, char *argv[])
{
  char *sz = "(Is this a correct warning???)";
  return main(1, &sz);   
}
----  end of test.c  ----

If compiled, it displays a warning

# gcc -o test test.c
test.c:3:42: warning: trigraph ??) ignored, use -trigraphs to enable
#
