I am using Windows 7 Home Premium and (from Help->About Emacs) "GNU
Emacs 23.2.1 (i386-mingw-nt6.1.7600)  of 2010-05-08 on G41R2F1", and
the value for system-configuration is "i386-mingw-nt6.1.7600". I guess
they have changed the format of system-configuration for Windows?? For
system-type I have "windows-nt".  Maybe sytem-type is a better
variable to check??
