Changes to code

     tzselect's diagnostics and checking, and checktab.awk's checking,
     have been improved.  (Thanks to J William Piggott.)

     tzcode now builds under MinGW.  (Thanks to Ian Abbott and Esben Haabendal.)

     tzselect now tests Julian-date TZ settings more accurately.
     (Thanks to J William Piggott.)

Changes to commentary

     Comments in zone tables have been improved.  (Thanks to J William Piggott.)

     tzselect again limits its menu comments so that menus fit on a
     24x80 alphanumeric display.

     A new web page tz-how-to.html.  (Thanks to Bill Seymour.)

     In the Theory file, the description of possible time zone abbreviations in
     tzdata has been cleaned up, as the old description was unclear and
     inconsistent.  (Thanks to Alain Mouette for reporting the problem.)
