vle test template error with gcc 4.9

[rtrepos]

Vle test utils/test_template does not work whith gcc 4.9.2 (on douar1 machine). Maybe this is due to lack of implementation of std::regex with gcc 4.9 ? The exception that occurs:

-- terminate called after throwing an instance of 'std::regex_error' what(): regex_error

--bactrace

The same error occurs with clang

[douar1:build] clang --version Debian clang version 3.5.0-10 (tags/RELEASE_350/final) (based on LLVM 3.5.0) Target: x86_64-pc-linux-gnu Thread model: posix

With clang-libc++ (clang-3.5 -std=libc++) it works. I update the documentation.
