Just edit your <signal.h> and move SIGINT definition to the ANSI part.

It should work after you move the definition and define a signal handler 
for SIGINT.  Note that if your program switches stdin to BINARY mode, ^C 
won't generat SIGINT unless you call `__djgpp_set_ctrl_c' with a non-zero 
argument.  Ctrl-Break always generates SIGINT.
