If I set the values as follows:

PREFERRED_VERSION_gcc = "4.5"
PREFERRED_VERSION_gcc-cross = "4.5"
PREFERRED_VERSION_gcc-cross-initial = "4.5"
PREFERRED_VERSION_gcc-cross-intermediate = "4.5"
PREFERRED_VERSION_gcc-cross-canadian = "4.5"
PREFERRED_VERSION_gcc-crosssdk= "4.5"
PREFERRED_VERSION_gcc-crosssdk-initial= "4.5"
PREFERRED_VERSION_gcc-crosssdk-intermediate= "4.5"
PREFERRED_VERSION_gcc-runtime = "4.5"
PREFERRED_VERSION_libgcc = "4.5"

I get the following warnings:

I've now got 3 gcc variants, 4.7 (in poky), 4.6 and 4.5 (in meta-openembedded), and it's automatically picking up 4.6, from the meta-openembedded/toolchain-layer.

After gcc_4.6 recipe builds, and I attempt to re-run gcc_4.5, I get the following output:

At this stage, 4.7.1, 4.6.3 have been built, but it doesn't allow me to build gcc_4.5 recipe.
