This is a bug report for perl from eroode@barrack.com,
generated with the help of perlbug 1.35 running under perl v5.8.8.


-----------------------------------------------------------------
[Please enter your report here]

To reproduce this problem, type the following command:

    perl -MPOSIX -le 'print POSIX::strftime("%Z",0,0,0,26,2,108)'

I tested this on three cygwin systems, all running perl 5.8.8, and
on each, the above command hung with the CPU pegged at 100%.

I tested under Windows/Activestate perl 5.8.8, and it worked fine.
A friend tested under Mac OSX with perl 5.8.8, and it worked fine.
This friend also tested on cygwin with 5.8.8, and it hung for him.

My POSIX.pm says its $VERSION is 1.09.
