Thanks for fast reply.

I did that change, and tried the "nmake /f libpqxx.mak ALL > x.txt" and got:

OK, to fix that problem temporarily you should edit connection_base.hxx
and change line 600 (or so, I'm looking at a slightly different version):

  void set_capability(capability) throw ();

into

public:
  void set_capability(capability) throw ();
private:

This will fix your build problem for now. I will look into a more
permanent solution with Jeroen, which we'll put in the next release.

The C API is much more complicated to use than libpqxx, so I don't think
that would be a good idea!
