Sorry for the delay.  I just checked in a patch.  I put the types in time.h near 
the declaration of _tzset_r.  I also added a new function __gettzinfo() which 
gets access to some variables that were previously declared global and are used 
by the other time functions.  For example, the __tzrule array.  I changed 
_timezone in _tzset_r to be long as requested in another post.  For Cygwin, I 
left it asis as I imagine you will have to change it on the other side as well. 
  If you are ok with making _timezone long, just change libc/include/time.h and 
remove the added flag.

I noted that for Cygwin you #define timezone to be ((long int)_timezone) in 
certain instances.  This has a problem in that elsewhere there is a struct 
timezone declared (reent.h).
