I've just discovered that libpq++'s makefile uses whatever is defined as
CXX for the compiler.  It's defined as c++, which is ver 2.7.2.1 here.
When I force it to use g++28 (ver 2.8.1), it misses /usr/include/g++.
Adding that to the list of CXXFLAGS fixes that.  Now then..  Will it
break something on another platform if I were to leave that in the
list?  Anyone know?

Also with g++ 2.7.2.1 and 2.8.1 I can't duplicate the problem that Dan
mentions above.  Dan, what compiler/compiler version are you using???

Vince.
