[C++-sig] Build Errors Making the "quickstart" Demo Project

[Niall Douglas]

If I am understanding you correctly, your attempts to build and/or 
use stock BPL is failing when building the quickstart demo?

If so, there is surely some issue with your build environment as 
Boost runs a series of automated regression tests which catch build 
failures.

If I'm not right in understanding you correctly, please do explain 
further.
