Subject: [PATCH 25/25] 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.
