From 60db5736604583fe99dde3c25412d97f9b77489d Mon Sep 17 00:00:00 2001 From: Erik Verbruggen Date: Mon, 26 Mar 2012 15:18:01 +0200 Subject: [PATCH] [C++] Rewrite of the preprocessor. This rewrite fixes a couple of issues with the pre-processor. It now supports: - macros in macro bodies - stringification of parameters [cpp.stringize] - the concatenation operator [cpp.concat] - #include MACRO_HERE - defined() inside macro bodies used in pp-conditions.
