BTW, while doing some minor fixes, I realized I still have generic
names for "warning", "pr_stat" and "vpr_stat" and thought they should
be changed to "tep_warning", "tep_pr_stat" and "tep_vpr_stat" for
namespace reasons even though they are weak functions. Would this
require a major version change, or perhaps its early enough to get this
in with a minor version change as the libraries are probably not being
used yet?
