Original Pull Request Message

 add a USA locale for windows 7 server

Testing on a local windows 7 server outputted locale info as "C" (no
locale info at all). The locales 'en_US', 'en_US.utf8', 'en' are not on
this server, while  'English_United States.1252' is. This shows up
correctly. Maybe the check
if ($loc !== FALSE) echo ' - ' . $loc;
needs expanding.
