IMHO wpkg.js should stop immediately if invoked in 32 bit context on a 
64 bit system (or better: in another context than stored in wpkg.xml) 
unless forced to continue by a command-line option. Sometimes wpkg.js 
may be run in the wrong context simply by accident. wpkg.js always uses 
the same wpkg.xml, but packages commands and checks will behave 
different. So this will be a source of troubles, and the cause may be 
hard to detect for the unexperienced wpkg user.
