But I am: I did an rm -rf of my build directory, and also removed ONLY
the linker from the install of binutils; but I was still using gas.  That
is what prompted the ld error (YES, I am absolutely, positively sure
that there are no other copies of the gnu linker around).  Rebuild
with only the --with-gnu-as flags, and that genattr misalignment happened.
rm -rf'ed the entire binutils directory and build directory, recompiled
egcs without the --with-* flags, and the misalignment goes away.

I am using binutils 2.8.1, and AFAIK a clean install of 4.2.0.  I don't
know if there are any patches to the OS installed on it, we really dropped
the ball on that machine.  (we don't even have the man pages on the damned
thing).  I'm gonna see if I can't talk my boss into re-installing the OS
on the monster :)
