From 4a6aca7bf8a70f1dc66a07c04aba2d7fd837602d Mon Sep 17 00:00:00 2001 From: Siddhesh Poyarekar Date: Mon, 29 Dec 2014 17:37:54 +0530 Subject: Remove Wundef warnings for specification macros This patch adds a file posix-conf-vars.list that is used to generate macros to determine if a macro is defined as set, unset or not defined. gen-posix-conf-vars.awk processes this file and generates a header (posix-conf-vars-def.h) with these macros. A new header posix-conf-vars.h includes this generated header and defines accessor macros for the generated macros. Tested on x86_64. * posix/Makefile (before-compile): Add posix-conf-vars-def.h. ($(objpfx)posix-conf-vars-def.h): New target. * posix/posix-conf-vars.list: New file. * posix/posix-conf-vars.h: New file. * posix/confstr.c: Include posix-conf-vars.h. (confstr): Use CONF_IS_* macros. * posix/posix-envs.def: Include posix-conf-vars.h. Use CONF_IS_* macros. * scripts/gen-posix-conf-vars.awk: New file. --- posix/posix-conf-vars.list | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) create mode 100644 posix/posix-conf-vars.list (limited to 'posix/posix-conf-vars.list') diff --git a/posix/posix-conf-vars.list b/posix/posix-conf-vars.list new file mode 100644 index 0000000000..8f308c2166 --- /dev/null +++ b/posix/posix-conf-vars.list @@ -0,0 +1,22 @@ +# Configuration variables identified by getconf.
