I have looked into the octave source a little bit more in detail.

In src/sysdep.h

#if defined (__WIN32__) && ! defined (_POSIX_VERSION)
extern void MINGW_signal_cleanup (void);
#define USE_W32_SIGINT 1
#define MINGW_SIGNAL_CLEANUP() MINGW_signal_cleanup ()
#else
#define MINGW_SIGNAL_CLEANUP() do { } while (0)
#endif

the definition of USE_W32_SIGINT is found.

In addition, sysdep.h is included from the sighandlers.cc.

Perhaps SetConsoleCtrlHandler is used for windows native version (not cygwin).

For the description of the development branch, the gnulib sinaction, 
sigprocmask and signal.h are
used.  However, they seemed not to have the SIGINT related modifications.
Perhaps even in development source the function SetConsoleCtrlHandle might be 
used.

However I cannot say the aboves are correct with confidence.

Can somebody else give more definite relies on this matter?

Regards

Tatsuro
