>Description:
Running bootstrap using the prebuilt GCC Alpha binaries (from ftp://ftp.NetBSD.org/pub/pkgsrc/misc/tnn/) leads to an odd failure upon running bootstrap.  Following the included README.OSF1, I run the command:

# env CC=/usr/local/gcc4/bin/gcc CFLAGS=-O2 ./bootstrap --compiler gcc

After doing some work, I eventually end up with:


...
You can now run

        sh ./make-bootstrap.sh

to produce a fully functional bmake.

===> running: (cd /usr/pkg/pkgsrc/bootstrap/work/bmake && /sbin/sh make-bootstrap.sh)

>How-To-Repeat:
On Tru64, enter the pkgsrc bootstrap directory and run:

env CC=/usr/local/gcc4/bin/gcc CFLAGS=-O2 ./bootstrap --compiler gcc
