+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.
+
+Upstream-Status : Submitted [https://sourceware.org/ml/libc-alpha/2016-08/msg00746.html]
