custom gcc article outdated?

[Anton Shterenlikht]

Is this arcticle outdated:

http://www.freebsd.org/doc/en_US.ISO8859-1/articles/custom-gcc/

Specifically, is this form still understood:

Add the following lines to the /etc/make.conf file (or modify appropriately):

.if !empty(.CURDIR:M/usr/ports/*) && exists(/usr/local/bin/gcc44)
CC=gcc44
CXX=g++44
CPP=cpp44
.endif

*end quote*

Thanks
