-// This is cheap hackery.  GDALUtils is the first file compiled, and
-// we want to make sure we have the correct boost before we go and
-// compile a bunch of junk.  boost::phoenix has a sub-namespace
-// called boostphoenix that gets renamed pdalboostphoenix as part of the
-// bcp extraction process.  If the user is using embedded boost, we can
-// know right away based on this sub-namespace.  All of the boost
-// headers do boost=pdalboostphoenix; for a top namespace, however, so
-// merely testing that is no good.  If someone has a better sub-namespace
-// than the one out of phoenix which probably includes half of boost in the
-// process, please switch this.
