Hi folks,

Finally submitted a patch I believe should be close to acceptable.

Attached are a test program kludged to build and run under Cygwin, and a 
shell script to run it, to test against all the unique POSIX fallback 
rules added as a line at the end of each of the /usr/share/zoneinfo/ 
files, and the result log from the test run dumping the input and 
internal tz data structures.

Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada
