The test tails for both HP-UX and Linux on IA64. It looks like the problem is
with the %VAL function on the f_to_f subroutine call. I believe that the
Fortran front-end is doing something wrong so that the %VAL(a) gets passed in
an integer register instead of a floating point register. Since a is a
floating point variable and it is being passed by value, the IA64 ABI says it
should be passed in a floating point register and that is where the C code is
expecting it.
