/*
 *	for diffent os, define tos, unix, or minix. for gemdos, pick
 *	a compiler (alcyon, mwc, etc). see makefile for VERSFLAGS.
 *
 *	for atari TOS, do:	cc -Dtos -Dalcyon ...
 *
 *	for minix, do:		cc -D_MINIX -D_ST ...		(ST minix)
 *				cc -D_MINIX ...			(PC minix)
 *
 *	for unix, do:		cc -Dunix ...			(generic)
 *				cc -Dunix -DBSD...		(BSD)
 *
 *	note: so far there is no specific ST minix version. -D_ST is ignored.
 *
 *	nroff uses index/rindex. you may need -Dindex=strchr -Drindex=strrchr
 *	as well. this file is included in "nroff.h" which gets included in all
 *	sources so any definitions you need should be added here.
 *
 *	all os-dependent code is #ifdef'ed with GEMDOS, MINIX_ST, MINIX_PC,
 *	MINIX, or UNIX. most of the differences deal with i/o only.
