No.  I can't think of any way to do that without making virtual
function calls less efficient at runtime.

GNU/Linux has a prelinker which can do this.  But the dynamic linker
has to recognize the prelinking, and presumably the Solaris dynamic
linker won't recognize what the GNU/Linux prelinker does.  I don't
know whether Sun provides any similar prelinking functionality for
