I suppose I should show you mine, then

$ LANG=C.UTF-8 ./Xlocale
Setting locale from LANG failed
Locale is C
XSupportsLocale returned true

$ LANG=en_US.UTF-8 ./Xlocale
Setting locale from LANG succeeded
Locale is en_US.UTF-8
XSupportsLocale returned true

$ unset LANG

$  ./Xlocale
Setting locale from LANG succeeded
Locale is C
XSupportsLocale returned true

$ uname -a
CYGWIN_NT-5.1 byron 1.7.0(0.212/5/3) 2009-09-11 01:25 i686 Cygwin

Okay, well this makes sense now :-(

Appropriate data needs to exist in /usr/share/X11/locale for the C.UTF-8 
locale, but it doesn't at the moment. Let me see if I can find it :-)
