I've seen this done, and it was extraordinarily painful.  To me the need
for this is a vote in favor of supporting this feature request, no
against.  Having said that, the only reason I know of that any of this
should actually be required is in an environment where only static linking
is allowed (e.g. a game console).

Is there a reason the requester could not just link to Boost dynamically?
