The nan_inf_fmt.f90 failures also occur in gcc 4.2 branch. Can we apply this
fix there as well?

I'll take this one since I've got the apple radar on it as well, removing
Geoff.

This is completely a target bug, and I have made a simple C testcase. I filed
this with Apple bug reporter under id# 4820385. Adding geoffk in CC list since
he wanted a C-only testcase, and now we have one.

$ cat ppc_longdouble.c 
#include stdlib.h
#include stdio.h
#include math.h

void foo_ (long double *y)
{
  long double x;
  int n;

  x = *y;
  n = isfinite(x);
  if (n == 0)
printf (!finite: %d %Lg\n, n, x);
  else
printf (finite: %d %Lg\n, n, x);
}

int main (void)
{
  long double x;
  x = 0.0;
  x = 1 / x;
  foo_ (x);
  return 0;
}
$ gcc-4.0 -g ppc_longdouble.c -O0  ./a.out
finite: 1 inf
$ gcc-4.0 -g ppc_longdouble.c -O1  ./a.out
finite: 1 inf
