[Nestedvm] building c++ with nestedvm-2009-08-09 snapshot

[Alexander Bertram]

Hi Aaron,

Just encountered the problem building on a newer Ubuntu distro. Nestedvm
builds a toolchain based on gcc 3.3.6 and g++  3.3.6 will not compile with
gcc-4.1, apparently because gcc-4.x is much stricter about enforcing certain
standards.

I was able to solve the problem by doing a full native build and install of
gcc 3.3.6 on the host, and the starting over with the nestedvm building
using gcc 3.3.6

These instructions were helpful :

Best,

Alex
