Using mec26. Sorry, forgot to mention this. (I suppose mec25 above is just 
a slight slip?)

System for the figures above is Win2k, for my original post Win95.
sh-2.04$ gcc --version
gcc.exe (GCC) 3.2 (mingw special 20020817-1)

This debug build I compiled with -ggdb, no optimisation. It was a fresh 
build from CVS 2 or 3 days ago.
