Sorry, I missed this.  The following test (reduced from
libgfortran/intrinsics/c99_functions.c) fails for me:

$ cat iround.i
float roundf (float x);

long int
lroundf (float x)
{
  return (long int) roundf (x);
}
$ ./cc1 -quiet -O2 -march=pentiumpro iround.i
$ cat iround.s
        .file   "iround.i"
        .text
        .align 16
        .globl  lroundf
        .type   lroundf, @function
lroundf:
.LFB0:
        .cfi_startproc
        jmp     __builtin_iroundf
        .cfi_endproc
.LFE0:
        .size   lroundf, .-lroundf
        .ident  "GCC: (GNU) 4.7.0 20110819 (experimental) [trunk revision
177911]"

I'll try the patch next thing.
