From 3c06f6a0b234822c7b2d6c63ef1aaf554af7167b Mon Sep 17 00:00:00 2001 From: Ben Lindstrom Date: Wed, 31 Jan 2001 21:52:01 +0000 Subject: - (bal) Reorder. Move all bsd-*, fake-*, next-*, and cygwin* stuff to openbsd-compat/. And resolve all ./configure and Makefile.in issues assocated. Logic: * All OpenBSD functions should have the same filename as in the OpenBSD tree * All 'home brew' functions have bsd-* infront of them. * All 'not really implemented' functions have fake-* infront of them. --- bsd-setenv.c | 161 ----------------------------------------------------------- 1 file changed, 161 deletions(-) delete mode 100644 bsd-setenv.c (limited to 'bsd-setenv.c') diff --git a/bsd-setenv.c b/bsd-setenv.c deleted file mode 100644 index d69f88258..000000000 --- a/bsd-setenv.c +++ /dev/null @@ -1,161 +0,0 @@ -/* - * Copyright (c) 1987 Regents of the University of California. - * All rights reserved. - * - * Redistribution and use in source and binary forms, with or without - * modification, are permitted provided that the following conditions - * are met: - * 1.
