Thanks! Now I can _finally_ throw away all <cxxflags> hacks!

I've noticed a couple of minor problems:
1) In pch.jam:
=================
# Make mypch.hpp a pre-compiled header (PCH) using mypch.cpp as the 
source file:
#    pch mypch : mypch.cpp mypch.hpp ;
=================
But this won't work because hpp must be the first in the sources list 
(BTW, may be an order-independent syntax will be better?).

2) PCH support won't work if precompiled header has ".h" extension and 
not ".hpp".
