With the move to convenience libraries we have been taking the approach of
removing static for things which are in any of the library API. If it does
not need to be visible outside the convenience library then its defined
internal to the .cc instead and the static maybe kept.
Converting the radix code to C++ matches the end-goal of fully C++ code.
If you want to take it on go ahead. It is a larger change though and
outside the scope of simply fixing build issues.
Tumbling down to a second side project of implementing inside configure
'benchmark' micro- unit tests that compare performance and size of several
implementations (STL, Boost, Squid custom, other) and makes Squid build
with the a) fastest, or b) smallest footprint. This is a major side project
though.
