WARNING: some systems have 'int' returning signal handlers, others
have 'void' returning signal handlers. Since the ones, which expect
a 'void' return type, will silently ignore the return value
at run-time anyhow, we can keep things simple here and just
specify 'int'.
However, this will cause a set of compiler warnings to appear;
which will be compiler _errors_ when we're compiling the setup
code in C++ mode; hence the forced use of an 'extern "C"'
setup function for this; see the internals in main.cpp...
The 'subcode' is in the arg list for the SIGFPE handler.
typedef int (*signal_handler_f)(int signal_code, int sub_code);
