[svn-r14607] Purpose: Apply Cygwin patch to trunk

Description:
This is the same patch that Mike McGreevy helped me with on the 1.8 branch.  The latest cygwin DLL has trouble with the global timezone variable.  Now in configure, we target CYGWIN with a case statement, and avoid the problem.

Tested:
Cygwin on WinXP
