+// 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.
+// Include limits std C++ header, so we get the version macros defined:
+#if defined(__cplusplus)
+# include <limits>

+// Check if libstdc++ is from GCC
+#if defined(__GLIBCPP__) || defined(__GLIBCXX__)
+// Check if version could be 4.8 or lower (this also matches for some 4.9 and
