It is ironic that when the GNAT project started up, one of the first
decisions we made was that, unlike all other Ada compilers previously
built, we would not do the equivalent of precompiling headers (in Ada
this translates into precompiling package specs into a library). That's
always proved a good decision for Ada.
I wonder just how much gain PCH's give you in g++, especially *after*
installing Mark's new c++ parser ...
