c++ wrappers

Are the progresql c++ wrappers ready for prime time?
I am having some problems with them while trying to
compile and link on my RH6.2 machine:

(1) Some of the headers have the following comments:

     *   NOTES
     *      Currently under construction.

(2) Compiling gives the following warnings:

    testlibpq.cpp:56: warning: comparison between
    `enum ConnStatusType' and `enum ExecStatusType'

(3) Linking fails with the following messages, eg.

    /tmp/cc91anuM.o: In function
`__malloc_alloc_template<0>::oom_malloc(unsigned int)':

/tmp/cc91anuM.o(.__malloc_alloc_template<0>::gnu.linkonce.t.oom_malloc(unsig
ned int)
    +0x17): undefined reference to `endl(ostream &)'
    ...etc...
