From 161d1bec16764585e987c8d804df0fb560a0d491 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Wed, 6 Nov 2013 07:36:46 -0700 Subject: [PATCH] don't check for stddef.h gdb already unconditionally includes stddef.h in many places. I think there is no reason to check for its existence. Also, Zack Weinberg's header file survey agrees: http://hacks.owlfolio.org/header-survey/ This patch removes the configure check and the inclusion guards. It also removes a redundant inclusion that I noticed in defs.h. 2013-11-18 Tom Tromey * config.in: Rebuild. * configure: Rebuild. * configure.ac: Don't check for stddef.h. * defs.h: Unconditionally include stddef.h.
