I'm waiting for it too.  My A3000 was installed a week ago with 1.3.2, has a
-current kernel, and is waiting for the libc "build OK" message.

Some problems were reported by others on libgnumalloc.  There were more
codegen fixes than just the vfprintf-triggered one before the egcs 1.1
release, so we'll see.

Possibly.  I know m68k assembly much better than the rest, so I'll take a
stab at looking at an objdump if it recurs.

Ick.  This probably should be looked at more closely.
