The corrected prototype for rb_gc_mark() [from the latest CVS sources
for Ruby 1.6] is:

	void rb_gc_mark(VALUE);

and so you should "fix the fix" accordingly. You are absolutely correct
that in FXRuby releases 1.0.12 and earlier, the instructions were to
change the prototype to expect a void* argument, which was consistent
with the implementation of rb_gc_mark() at that time. When this
prototype was "officially" corrected in the Ruby 1.6 sources, I changed
the build instructions accordingly -- but I failed to make a big deal
about it in the change history for the 1.0.13 release (my oversight).
