    But the big question is, why when I use the default -O2 and don't specify 
    --without-x does it built just fine !?

    the optimisation error obviously only relates to stuff that's included for 
    emacs when there is no X support. any ideas?

You can try compiling various files with different flags
and determine which file is the locus of the problem.

Then you can try splitting that file into two parts, compiling each
part differently, and moving some things between the parts.
then you can find which function is the locus of the problem.

Then someone could study the erroneous assembler code made for that
function and try to find the GCC bug.

But before trying any of this, how about if you install the latest GCC
release and see if it still fails.  There is no point in your spending
time to debug a GCC bug that has been fixed already.
