Yes, I guess that would be the way to go. I don't really know enough
about jam to do this with any confidence. The only way I could think
of would be to introduce a new variable, which is either empty or set
to enable-auto-image, and include this in the assignment to
IMPLIB_COMMAND somehow.

I've tried doing something like the following *after* the current
assignment:

if $(NT) {
# Give the enable-auto-image-base option to the linker as well
IMPLIB_COMMAND on $(<) = "-Wl,--enable-auto-image-base " +
IMPLIB_COMMAND ;
}

But this doesn't seem to pick up the previous value. Is this even
possible? How would a real jam programmer do this kind of thing?
