Boost wouldn't be the entity redistributing the helper code, so that 
reduces the problem somewhat.

I'm just not sure how much effort boost developers would be willing to put 
in to accommodate legacy operating systems which already have workarounds 
available from several sources. The issue may be moot anyhow. If Win9X is 
treated as a dual wide/narrow system (which we may do anyhow), and a 
program only uses narrow paths, then the wide API functions will never be 
called.
