Could you post or have a look at libc_plan9.h - that file is generated by stripping out some things from /sys/include/libc.h and it appears that something in that process has generated a syntax error.

I also downloaded the go hg tip and did this: cd src ./all.rc I now get errors quite early itself while building lib9.a. Attaching a screenshot. I still can't seem to copy text to/from virtualbox.
