I downloaded the gcc 2.7.2p-pl9 patch from 
<http://goof.com/pcg/data/gcc-2.7.2-2.7.2p-pl9.diff.gz>, 
then applied it against the version of gcc in NetBSD-current as of
last June.  I also made a few changes, such as renaming all of the 
binaries and libraries from <name> to p<name>, so they can
live alongside the standard gcc (although I only use pgcc now).

I still have the diffs against NetBSD gcc, if anyone is interested.



I think the key with using pgcc is patching the NetBSD version of gcc,
not the standard 2.7.2. If I remember correctly, my first attempt at 
using pgcc was just a patched version of standard gcc 2.7.2 - that 
version failed miserably, especially when trying to compile the kernel.
