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. --- ChangeLog | 9 +- Makefile.in | 15 +- bsd-arc4random.c | 71 ---- bsd-arc4random.h | 35 -- bsd-base64.c | 316 --------------- bsd-base64.h | 16 - bsd-bindresvport.c | 123 ------
