* app/composite/gimp-composite-3dnow.c:
  Incorrectly reported the inverse of whether not the 3dNow instruction set is
	supported by the current CPU.

* app/composite/gimp-composite-{mmx,sse}.c:
  Removed linkage of gimp_composite_divide_*.  Something is
  inexplicably broken, and this will get people working again
  while I debug.  This should close bug #125101.
