BTW, the man-page for ld mentions an optimization option -On -- does anyone know what the affect of this option is and whether its GNU specific ?

Yes, it is GNU specific. It currently (binutils 2.11) only supports one level of optimization, and that is only used for ELF targets. On ELF targets, if optimization is requested, the optimal table size for the symbol table is computed. Since ELF uses a hashing mechanism, the number of hash collisions depends on the table size. Under optimization, the linker tries all table sizes, and choses the one with the least collisions.
