Loading a mapfile from a string...

I have been using
http://gnuwin32.sourceforge.net/packages/flex.htm

Currently there's no binaries available on Windows for the newer
version. I would propose to add the generated files of flex and bison
to the CVS tree in order to make the life easier.

Best regards,

Tamas
