 /*! \brief Names of the GPU detection/check results

+ * Check-source wants to warn about the use of a symbol name that would
+ * require an inclusion of config.h. However the use is in a comment, so that
+ * is a false warning. So C-style string concatenation is used to fool the
+ * naive parser in check-source. In turn, that needs a clang-format suppression
