I have a suite of programs developed under TurboC, which I have
transferred to GnuC, using go32.  There is a slight problem that I have
observed.
When a call to system fails, then the value returned is 0.  This can
happen for example if a TurboC main program executes

	rc = system("gcc_prog ...");

and go32 is not in the PATH, or if the gcc_prog is interrupted by ^C.
In either case, system returns 0.  Should it not return some non zero
value?  (I don't know what UNIX does)
