I tried '--jobs=10' and it failed. That seems to suggest that at least
one file requires an extraordinary amount of RAM. The 'cc1plus' messages
below don't seem to indicate that, so maybe there's a nearby file that
ate all the RAM so that there was none left for the less hungry ones.
I doubt many people are building wx with this degree of parallelism in
32-bit msw-xp, but perhaps others would try it in a RAM-limited VM.
