true, it has incomplete c++ support, but i think ragge is working on it.

i am looking to build as much of netbsd (without x11) with pcc as possible.
this is a purely tinkering and experimenting project.
may i know which parts of netbsd don't build with pcc? and why?

also, i'm still quite raw at netbsd, but, is it possible to eliminate
portions of the netbsd kernel and build a fresh, highly focused and optimised
system for amd64 architectures? and yet be able to tap into pkgsrc?

gcc is nice, but massive, on the other hand, pcc is quite nimble. :)
