There are two standards in play. The UNIX standard recognizes CET-1CEST. 
The zoneinfo standard recognizes Europe/Monaco. All UNIX systems 
implement the UNIX standard; many implement zoneinfo also. The GNU CRTL 
implements both. The Windows CRTL implements the UNIX standard (actually 
it implements a subset) but does not implement zoneinfo.

You could link cygcheck to the GNU CRTL instead of the Windows CRTL, but 
that defeats cygcheck's purpose.
