The attached patch for bug 238753 makes base.eclass support EAPI 2 
functions. None of the previous functionality of exported functions is 
changed, so you can still do base_src_unpack autopatch. It's only the 
default actions of base_src_compile and base_src_unpack that's affected 
and only if EAPI=2. The case..esac for EXPORT_FUNCTIONS is borrowed 
from kde4-base. I've not done tree-rebuilds with this, so please give 
it a thorough review. I'm not entirely happy about the base_src_work 
and base_src_util function names, so suggestions are welcome.
