Fair enough.  The tests were in a separate patch file anyway so they're 
easily excluded.  It was more for my benefit anyway because my computer 
is not the most high-end and frequently runs out of space (one reason 
why I proposed using SLEB128 and ULEB128 for some of the fields in 
compiled PPU files, even if partial recompilations took 4 seconds 
instead of 3 seconds), so I can really only run one configuration 
overnight (once for the trunk, once for the patches I'm testing under 
i386-win32, and then again for x86_64-win64.  Linux requires some 
additional work, but tends to run faster than Windows for me even when 
using a virtual machine, probably because it's more streamlined with 
starting new processes).
