From 55ba8c022b493b494bea257e4f523758154e0fdd Mon Sep 17 00:00:00 2001 From: Paul Eggert Date: Fri, 16 Oct 2015 14:54:09 -0700 Subject: Make src headers idempotent and standalone Redo src/*.h so that each include file is idempotent (that is, can be included multiple times with the latter inclusions having no effect) and standalone (that is, can be included by itself, with no include file other than config.h needed as a prerequisite).
