That's probably because the stack pointer points at
the wrong end of the stack. There are some magic
#defines you can put in that change the meaning of
the stack pointer field that you pass to makecontext
on Solaris. In one mode you set ss_sp to point at
the top of thestack; in the other mode, the bottom.
The different versions of Solaris differ on which mode
is the default and whether the other mode is even
available. This is the specific reason I gave up. If someone
lined up Solaris 5.8, 5.9, and 5.10 boxes and wrote
code that worked on all of them, that would be fantastic.

You may be able to solve your particular problem by
changing that #if to #if 1.

Once you get the thread library working,
you will probably have to add support for
the Solaris FS to libdiskfs, unless it is the
same FFS that BSD uses.
