This was gcc 3.4.x and 4.0.3 on solaris 5.10, but on a machine that I
suspect doesn't have enough administrative TLC to have properly
installed tools. So unless someone else reports the same issue, let's
ignore it.
FWIW, I had difficulties using the generated binaries on the machine
because they sucked up too much entropy from /dev/random. Sigh.
