The file resulting from using -save-temps

This code uses Boost extensively, although I don't know if that has any bearing
on the matter.

You need to make sure to include the pch only from the toplevel source. 
Otherwise
interesting things may happen.  A convenient way to do so is to include the
pch via the -include command-line option.

Hmm... I have ensured that the #include chain in every source file results in
the given header appearing first.  That is, whatever a file includes, it will
include utils.h, which includes system.hh.  And so, it works with 4.2 just fine
(I checked using -H, to ensure the includes it actually does process are the
right ones).  So why would it start crashing with 4.3?

Also, -include is not a portable option.  I'll just reorganize my code.  Thanks
for the quick response!!
