- * 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.
