[K42-discussion] Warning: MakePaths.proto change

[Maria Butrico]

We made a slight change in the way in which the gcc3 compiler is picked up.
I hope it does not cause any troubles.

(You need do nothing,  I am sending this as a warning, in case someone
starts seeing some errors in build and cannot easily relate them to this
change)
