From 2c0ab83eb54c0e0fccbf261726dc03803b236079 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?J=C3=A9r=C3=A9my=20Rosen?= Date: Mon, 22 Aug 2016 16:09:25 +0200 Subject: [PATCH] locale: fix hard-coded reference to gcc -E When new version of compilers are published, they may not be compatible with older versions of software. This is particularly common when software is built with -Werror. Autotools provides a way for a user to specify the name of his compiler using a set of variables ($CC $CXX $CPP etc.). Those variables are used correctly when compiling glibc but the script used to generate transliterations in the locale/ subdirectory directly calls the gcc binary to get the output of the preprocessor instead of using the $CPP variable provided by the build environment. This patch replaces the hard-coded reference to the gcc binary with the proper environment variable, thus allowing a user to override it.
