Yes.  I used --with-gdktarget=win32 --prefix="c:/gtk"

Is there a way I can check?

There were complaints about --export-dynamic.  I changed one instance of
--export-dynamic to --export-all-symbols in the configure script, not
seeing where I could have effected this change through env vars.

If I limit the number of data points to display to around 100,000 the
graph does get displayed on Win32 (Windows 7), but it is very much
slower than on Linux.  I'm considering whether I need to effectively
produce decimated data for when the view spans more than say, 10000
points.

Regards,
James.
