It's feasible to perform valid tests, but it requires some care and
planning.  Whenever you're changing a system header file, write
it down.  When you are done making changes, re-install the virgin
unadulterated copies of those header files.  In general, do your best
to restore your system to a pristine state.  Then test with make
world.

Yes, this is a pain.  But it's a pain for one person instead of for
several hundred. :-)
