Yeah, along with the all other docs I've promised to rewrite, and the
permissions I have to obtain for the shared_ptr code, no problem! ;-)

Seriously, I haven't used PCH for anything but trivial tests, because
they're broken on FreeBSD (and the impression I get is they're broken
nearly everywhere except Linux, though I think that's unfair and I've
had a bad impression of them.)  I did try a tr1.gch PCH as you suggest
and it worked OK (on Linux).

I *certainly* won't be tackling docs until my day job calms down and I
get the shared_ptr copyright issues resolved. btw, shall I commit the
two patches at these URLs or wait for the copyright issues to be cleared
up?  The first one is essential and the second one IMHO a good idea:
http://gcc.gnu.org/ml/libstdc++/2005-02/msg00185.html
http://gcc.gnu.org/ml/libstdc++/2005-02/msg00187.html
