Hi Stephen

I don't know if you've worked this out in the six weeks since you
posted your message :-)  Anyway, it looks like no one answered ..

The problem is that c-torture.exp does not access TORTURE_OPTIONS from
the environment, but from the Tcl global variable space.  The easiest
way to alter this it to use something like this in your site-local
`site.exp' file:

   global TORTURE_OPTIONS
   set TORTURE_OPTIONS [list {-O0}]

The right way is to define a new board that is derived from (say)
`unix.exp' but modifies the board settings you are interested in.  You
can then specify that target board with --target_board in your
RUNTESTFLAGS.
