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.
|
