Thanks.  Yes I have tried a few combinations including Os.

Interestingly the best combination so far is not the same for gcc3.0.1 as it is
for gcc2.96. The sizes of the compiled are also revealing
gcc3.0.1    498kB (same optimisations)
gcc2.96     393kB (same optimisations)
MSVC++      308kB

Something is clearly different in the way these compilers work, which is
intersting, but I do not know enough to suggest what.
