3.2.0 compile error on FreeBSD 7.2/amd64 (sig_atomic_t != int on amd64)

[Maho NAKATA]

Hello, John W. Eaton and all,

I have encountered Octave 3.2.0 compilation error
* octave 3.2.0 
* FreeBSD 7.2/amd64 [amd64 specific]
* 3.1.55 was okay both on i386/amd64.
* error log is following.

---------------------------------------------------------------------------
* possible reason
It happens on amd64 only, (not i386).
and relevant part pt-eval.cc:920 is:

>  unwind_protect_int (octave_interrupt_state);
>  octave_interrupt_state = 0;

however,
on amd64 sig_atomic_t is defined as
/usr/include/machine/signal.h:typedef long sig_atomic_t;
and on i386.
/usr/include/machine/signal.h:typedef int sig_atomic_t;

In this case, unwind_protect_long ? I'm not sure.
