Hi!

I've tried installing the stap unstable debian deb package, and when
running:

stap -kvvvve 'probe begin { log("hello world") exit () }'

I'm ending up with the following error:

 _stp_valid_stack_ptr
 __stp_stack_sprint
 _stp_kta
cc1: warnings being treated as errors

Pass 4: compilation failed.  Try again with more '-v' (verbose) options.

I'm running a plain self compiled 2.6.16.19 kernel.

Fooling around with the CC/CFLAGS environment variables didn't yield any better results.

Furthermore I've noticed that stap seems to clean out the CC envvar,
because despite me setting CC=gcc-3.4 it still issues a command
starting with gcc. 

Trying to cd into the tmp directory, and starting the compile manually
produces even more errors, so I wonder how I can compile the output in
the temporary?
