* pexecute.c (pexecute) [__MSDOS__]: Change __GO32__ to

__DJGPP__. Use P_WAIT instead of constant in the spawnv* call.
        Cast program to 'char *' in errmsg_arg assignment.
        (PWAIT_ERROR): Define.
	(pwait): Use PWAIT_ERROR.  Adjust DJGPP's status code to conform
        to DJGPP's WIF* macros.
