   HI!

   I am trying to port a unix application to dos. I am getting an error
   from GCC saying some labels are undefined. They are :

   SIGQUIT and SIGBUS

   Aparantley it expects to find these defined in <SIGNAL.H>. The
   <signal.h> file for the GCC with the DJGPP package doesn't define
   them. Does anybody know what they should be? Or, how to work around
   them?

   I have GCC 2.7.2 on my Linux system, and it doesn't define then
   either.

   I'd appreciate it if someone knows the answer to this one.

You could probably safely define them as follows:

#define SIGQUIT SIGINT
#define SIGBUS SIGSEGV

The SIGQUIT signal is a stronger version of SIGINT (like Ctrl-break -vs- Ctrl-C).
SIGBUS and SIGSEGV are subtle shadings of different kinds of address errors.
