Steven,

Libc 5 is really gone -- H. J.  Lu has just announced that he will do no
more work on it.  We certainly won't be using it anymore and therefore
likely even if we put your patches in now, they will gradually disappear
again.

Some things you say below I have no difficulty with, but other stuff I
don't think is necessary.

This will have to go into the #ifdef clause.  Most systems have register_t
and in that case we definitely don't want to redefine it.

This won't go in.  The coda.h file is the _only_ file shared between the
kernel and and userland.  I absolutely cannot include time.h without
running the risk of a time conflict.  Perhaps you can tell me what the
problem is in the compile, using MAKE CODA not just MAKE.

If you do make coda (not make) then all these symlinks are unnecessary.
The hdrinstall target (part of make coda) installs the include files in
the include directory.
