+ *  ---------------------------------------------
+ *  Explanation for Boost 103200 conditional code
+ *  ---------------------------------------------
+ *
+ *  This boost version has an implementation of the program_options library
+ *  that has no provision for allowing unregistered options to pass by.
+ *
+ *  But that means that, if you have a program that loads optional modules
+ *  after start-up, and those modules each have their own set of options,
+ *  then if you parse the command line too soon, you will get spurious
+ *  reports of unrecognized options -- and the program will exit!
+ *
+ *  And we must process the command-line before module-loading, because we
+ *  need to look at the "bootstrap" options.
+ *
+ *  This conditional code:
+ *
+ *      1. implements it's own functor class, derived from the Boost
+ *         "options_description_easy_init" class.  This functor is used
+ *         to process added options and do the functor chaining, so that
+ *         I can snoop on the arguments before doing an explicit call
+ *         to its parent.
+ *
+ *      2. It implements two static vectors, one to hold long names, and
+ *         one for short names, so that options declared by modules are
+ *         not forgotten when their options_description goes out of scope.
+ *
+ *  I will be thrilled to personally delete this code if we ever decide
+ *  that qpid doesn't really need to support this antique version of Boost.
+ *
