// In the libstdc++ headers that are provided by GCC 4.8, std::regex is not
// working correctly. In order to make features using regular expressions
// work, a replacement regex library is used. Just checking for GCC version
// is not enough though, because at least on RHEL7/CentOS7 even when compiling
// with Clang instead of GCC, the GCC 4.8 headers are still used for std::regex.
// We have to check the version of the libstdc++ headers specifically, not the
// compiler version. GCC headers of libstdc++ before version 3.4 define
// __GLIBCPP__, later versions define __GLIBCXX__. GCC 7 and newer additionaly
// define _GLIBCXX_RELEASE with a version number.
