I figured out what I was doing.  First, I was using Code::Blocks, and I had
removed from the project an older version and created a version to play wit=
h
for a while.  I was editing the new version ptl_interfaces.hpp, but I was
still calling ptl_interfaces.h (unchanged).  That got frustrating making
changes with no results.  Everything compiled fine when I changed to the
right header file.

   The problem that caused the problems is what Tom said in his reply.  I a=
m
new to using namespaces.  I just polluted the global namespace in the past.
Can you use includes & using namspace std inside a namespace? Why or why
not?  Like:

namespace ptl {
#include <map>
using namspace std;
 }
