If you go back to the Op's main concern, it is about VS PCH
limits with Phoenix3 at about /Zm160 and VC8's default: /Zm100
which is at about 75MB and "big" Boost libraries are around /Zm50.

Yes, things can be better today, but only to a certain extent.
This is one that I do not think we can fix other than to bump
to /ZM160 and beyond.
