Windows terminal and mintty both have support for link escape sequences, and so auto_enable_urls shouldn't be hardcoded to false. For older versions of the windows console, mingw_ansi_fputs's console API translation logic does mangle these sequences, but there's nothing useful it could do even if this weren't the case, so check if the ansi escape sequences are supported at all. conhost.exe doesn't support link escape sequences, but printing them does not cause any problems. gcc/ChangeLog: * diagnostic-color.cc (auto_enable_urls): Don't hardcode to return false on mingw hosts. * diagnostic-color.cc (auto_enable_urls): Return true if console supports ansi escape sequences.
