Summary:                    CHECK_C_COMPILER_FLAG does not work on non-English
locales
Description: 
The regular expressions that are used in 

CHECK_C_COMPILER_FLAG

only work for an English or C locale. On a German localized system e.g. the gcc
warning is not recognized if you pass a C++ option like
"-fvisibility-inlines-hidden" to gcc.

I think there are two options:

1. add some code to switch the locale before the test, like it is done in
CMakeExtraGeneratorDetermineCompilerMacrosAndIncludeDirs.cmake

2. try if -Werror or an equivalent is accepted first and then pass it together
with the option that should actually be tested
