Yup, there's our problem.  Your C++ setup is evidently pretty modern,
since it knows what namespace std is.  My guess is that you don't have
the headers for libstdc++ installed.

It would probably be a good idea to add another configure test to see
whether class "string" is actually available, and disable building
libpq++ if not.  (We shouldn't simply kill libpq++ if the "include
<string>" test fails, since older C++ installations may have class
string in <string.h>.  But if we can't find a header that defines class
string at all, then libpq++ is definitely going to fall over.)

Any objections if I sneak in such a configure test?  Should be a
low-risk change.
