I've built emacs 23 under both cygwin 1.5 and 1.7, and it runs fine for 
me except for a glitch involving time zones:  Emacs gets the local time 
zone wrong by 4 hours.  I've reported this to the emacs-devel list [1], 
and the developer who responded asked me to try to get some advice on 
this list.  Here are two facts that might provide clues:

1.  The problem disappears if I set the environment variable TZ before 
starting emacs.

2.  The problem disappears if I run emacs under gdb.  [This, of course, 
makes debugging difficult.]

I would appreciate any advice or hints as to how I (and the emacs 
developers) might track this down.  Also, the developers would find it 
useful to have a description of how cygwin handles Windows time zones.

Thanks in advance for any suggestions.

Ken
