"right" way to upgrade to gcc-4.4.1

[David <davidlxv773%gmail.com@localhost>]

Hello,

(Sorry for the HTML post, resending in plain text.)

pkgsrc head recently added support for gcc-4.4.1.  I've tried it and
it works well (save for a BUILD_JAVA crash).  I'd like to use
gcc-4.4.1 to rebuild the NetBSD world (seamlessly picked up by
build.sh) for i386 and a few cross targets.  My question is:  What's
the "right" way to replace gcc-4.1.3 with the now-working gcc-4.4.1?

Thank you,
-david
