One way to do it would be to add the following to the port:
.if ${_GCCVERSION} >= 040100
CFLAGS+= -Wno-pointer-sign
.endif
After the ".include <bsd.port.mk>" or ".include <bsd.port.post.mk>".
It doesn't work before the bsd.port.mk, or after the bsd.port.pre.mk.
You may want to ask the port managers to move USE_GCC into the
_PREMKINCLUDED section of bsd.ports.mk.
