   Someone ought to submit patches to them so that 2.7.1 supports NetBSD
   on most platforms out of the box.

um...

dynamo ~/gcc-2.7.0> grep -i netbsd configure | grep \\\)
	i[345]86-*-netbsd*)
	m68k-*-netbsd*)
	mips-dec-netbsd*)                  # Decstation running NetBSD
	ns32k-pc532-netbsd*)
	sparc-*-netbsd*)
	vax-*-netbsd*)

most of the platforms are supported already... even the vax..  :-)
