These signals are non-portable (neither ANSI nor Posix require them),
and DJGPP doesn't support them.  You can never have SIGBUS or SIGSYS
in a DJGPP program.  That's why you don't find them in signal.h.

Any portable code should only use non-standard signal names if they
are defined, like this:

    #ifdef SIGBUS
    put here the code that uses SIGBUS
    #endif

If the program you are trying to compile doesn't do that, I suggest to
report this to the program's maintainer.
