Is there a way to automatically make gcc color its output?

I am looking to avoid an alias as the the command is commonly used in makefiles (where it will not be used).

Is there an easy way to do this?

Note: this does require gcc/g++ 4.9, which is currently available via svn. I am willing to recompile if the change is something small (in a config file or something).

I know that the GCC_COLOR environment variable is used, but I am not sure how to set it, or what to set it to.

Add to your .bashrc:

export GCC_COLORS='error=01;31:warning=01;35:note=01;36:caret=01;32:locus=01:quote=01'

But note that GCC 4.9 is under heavy development, so the defaults may change.
