This is the current devel cvs which is comprised of patches from Dave
Miller and others (judging by the ChangeLog's). Merging with the main
egcs isn't possible since this is not a release source.

/lib64 and /usr/lib64 is how egcs compiles by default, so there are no
issues there.

Right, sparc64 should just be an overlay on top of sparc32. Problems
that will arrise have to do with dpkg/apt/dselect being able to
distinguish prefered builds (ie. prefer an arch=sparc64 over an arch=sparc
of the same package if available) or name the packages with a 64
extension somewhere (which would be horribly difficult to maintain just
for one port).

This isn't what I am seeing. By init failing I mean the actual binary
/sbin/init. I can get to a single shell as well, but this bypasses init
all together. I also have a kernel compiled without module support, so
it's not directly attributed to modules or module loading. What I see
is init starting and the system hangs right there.

I've also tried the 2.2.5 kernel, aswell as the cvs, and still have the
problem. Maybe sparc32-sigaction is a bad thing? The patch looks fairly
