Bill,

In case you are not familiar with the term 'universal build' it's Apple-
speak for 'doing multiple compilation passes, one per CPU type, and
merging the results into one library/executable'.  It's basically a
cross-compilation.  Our 'InsightBS' dashboards are built for 4
architectures: 32 bit PowerPC, 32 bit Intel, 64 bit PPC, and 64 bit
Intel.  Any kind of TRY_RUN to detect sizes or endianness breaks this
kind of build because the TRY_RUN runs once and the compiler runs 4 times.
