Are you sure? I definitely remember reading some stuff about "weak binding"
in the PE file format some time back. Useful for linking in floating point
code, but not actually including the code unless there was an actual call to
a specific floating point routine. This allowed you, for example, to use a
function like printf without linking every numeric (other other) conversion
routine known to man.

Couldn't say. I looked into all this stuff many years ago, but haven't
messed with it since. Try looking up "weak binding" or "weak external
linkage" or something along those lines involving "weak" and see what you
come up with.
