compile failure at ports/graphics/py-cairo on FreeBSD4.
pycairo sources use C99 style, not ANSI-C.
and pycairo's configure checks stdint.h, but source 'cairo/pycairo-surface.c'
#include stdint.h unconditionaly.
then, pycairo can be builded on gcc3/FreeBSD6, but cannot on gcc2.9/FreeBSD4.
patch is here (FreeBSD SendPR-system),
Applied the patch to CVS. stdint.h is no longer used so I removed it.
