Doug Coleman fb60673840 math.vectors: Don't use macro with locals and cond in vif. Stack-checker/locals/macros/smart-combinators all need some work (a rewrite?), but meanwhile don't let it get in the way. Add tests. 2013-01-03 09:49:31 -08:00

Doug Coleman 516549b52c basis: Try to fix the build. My profiler is hanging, but I can't figure out why. See if the build farm has the same is 
sue.
