Incomplete patch for XFree86-4-libraries?

[walt]

I had trouble re-compiling the X libraries on two -STABLE
machines.  That is, the portupgrade finished without
apparent problems, but when trying to build the libraries
a second time I got a compile-time error complaining that
GccWarningOptions was undefined.

I believe this is because patch-FreeBSD.cf is missing the
definition of GccWarningOptions.  I don't know why this
didn't cause problems during the portupgrade, but OTOH
mozilla stopped working at the same time, and recompiling
the X libraries got mozilla working again, so maybe there
was a non-obvious problem during the portupgrade.

Am I the only one seeing this?  Seems hard to imagine.
