What's missing:

- Support for integer(1/2).  The standard requires (13.7.167):

COUNT (...). It is assigned a processor-dependent value based on the
value of the processor clock, or −HUGE (COUNT) if there is no clock.

COUNT RATE (...) It is assigned a processor-dependent approximation to
the number of processor clock counts per second, or zero if there is
no clock.

COUNT MAX (...) It is assigned the maximum value that COUNT can have,
or zero if there is no clock.

  We might treat any integer(1/2) argument as there were no corresponding
  clock.  I just don't know how to create the corresponding code to
  set the result variable appropriately.

- The compile-time warning FX mentioned in comment #12.  We could
  split this one off as an enhancement.

- A consensus what shall happen for arguments of mixed kinds.

Shouldn't this net change be backported to gcc-4_9-branch for 4.9.3? We seem to
need it there...
