[Coco] MWC question

[Paul Fitch]

 I pulled the cc.dsk off of www.nitros9.org/latest

I set me PXD to /d1/cmds
I set my PWD to /d1/sources

I tried cc1 line.c and got the following text:

'line.c'
c.prep:
ERROR #001
c.pass1:
line.c : line 3 **** can't open ****
# include <stdio.h>
          ^
ERROR #001

So I copied stdio.h into /d1/sources and got the same error.

What am I doing wrong?
