how to switch the base compiler to gcc 4.4.2

[Saifi Khan <saifi.khan@xxxxxxxxxxxxxxx>]

Hi:

How does one switch the base compiler to gcc 4.4.2 ?

Here is some info for my setup:

 . running DragonFly 2.7-DEVELOPMENT v2.7.0.47.g3f16d 
   (HEAD as of April 4, 2010).

 . the HEAD was built with CCVER=gcc44 for
   - buildworld
   - buildkernel
   - installkernel
   - installworld
   - upgrade

 . /usr/libexec/gcc44 directory has
   CC
   c++
   c++filt
   cc
   cc1obj
   cc1plus
   cpp
   g++
   gcc
   gcov


 . have setup the following entries in /etc/make.conf
   CCVER=gcc44
   CC=gcc44
   CXX=g++44
   CPP=cpp44
   CFLAGS+=-mssse3

i donot see any /etc/libmap.conf (as seen in FreeBSD) which 
needs to be tweaked for rtld and ldd.

Any pointers as to how to make gcc 4.4.2 as the base compiler 
for my custom DragonFlyBSD system on AMD64 box ?
