 I've tried to add a gbuild rule to rebuild a PCH if its build flags change, 
but that's actually rather tricky - the PCH target would need to depend on a 
rebuild target, but the rebuild target would need the flags that are set only 
for the PCH target. It could possibly be handled somehow by making the rules 
more complicated, but I think in this case it's simpler to just do 'make 
clean' on the affected incremental tinderboxes. This kind of PCH breakage 
doesn't happen very often, or does it?
