Too bad that `intdoc.h0' has already been removed...ok, i bothered to
regenerate it. The preprocessed `intdoc.i' shows this:

[...]
#line 2498
{ FFEINTRIN_impDATE_AND_TIME, "Returns:\n..." },
#line 186 "./f/intdoc.c"
};

static char *summaries[FFEINTRIN_imp] = { 0 };
static struct cc_pair cc_summaries[] = {
#line 193
};

char *
family_name (ffeintrinFamily family)
{
  switch (family)
[...]

The compiler worries about the empty initializer for the cc_summaries array.
Unless somebody comes up with another explanation, I'd say there is a bug in
the xlC preprocessor. It works with gcc. The fix is probably to use gcc
instead of xlC.
