[winGRASS] libG11

[Malcolm Blue]

For everyone who is testing out the new native windows code:

I've just loaded to CVS a bug fix to the libG11 code that fixes the windows
memory leak in interactive calls.  Please update your copy of
libW11/w32/xlib.c and remake the library to get more enjoyment of the code.

This is (WAS) a fatal bug as you may have noted from some of the winGRASS
list postings (from the original code - not any of Mike or my fixes :) ).

Keep on testing.

Enjoy,

Malcolm

PS  I have cleaned up the event handling as per Glynn's advice, but it still
needs some work.
