ron is suggesting is that with minimal effort
the plan 9 kernel could be made to compile

he's right.
erik's point is that once you have a kernel up,
you still need to give it executables to run.
this either requires porting the standard compilers

Excuse me?
Instead of keeping that to yourself why not tell me so I can fix it?
I know many people who install from the tar file, though,
so I expect you're just whining in
Thanks, but I'm happy with the current tar files.
They are a working CVS checkout, so that
people who use them can then use the recipes
in cvs(1) [9 man cvs] to update their trees.
The one you linked to is not a working anything checkout.
I haven't touched the tar file generation in over a year
so
you are smarter than 8c.
just put sd = nil above your loop.
8c isn't smart enough to know that
the body of
for(i=0; i<2; i++)
because it does not make two copies
of the i<2 test, so it cannot determine
that the very first one is guaranteed to
succeed.

This problem is uncomputable, so trying to
handle every case that comes up is problematic.
There has to be a line somewhere. Saying that
the compiler could figure out does not imply
that it must.
I think it's perfectly reasonable that a compiler,
when presented with a program like
int x;
This is a kernel bug.
sysfile.c:/^read says
dir = c->qid.type&QTDIR;
if(dir && mountrockread(c, p, n, &nn)){
/* do nothing: mountrockread filled buffer */
}else{
if(dir && c->umh)
nn = unionread(c, p, n);
