gtk2/gdk/quartz/gdkevents-quartz.c
Kristian Rietveld b2b70e5a8d Start using NSInteger and NSUInteger 
These have been introduced in Leopard and default to int and unsigned int.
In 64-bit Snow Leopard they are long and unsigned long.  This caused issues
with the getRectsBeingDrawn message which needs a pointer to a NSInteger
(long on 64-bit!) but we passed in an integer.  Surprisingly this problem
was visible when compiling with -O0 (segfault), but *not* when compiling
with -O1.  Other messages were NSInteger is now needed have also been
adapted.

Since NSInteger and NSUInteger are not available on Tiger, a define
has been added to add typedefs for these when they have not been defined
by the system headers.
