Good. I think that the patch has already been applied to the 6.5 branch
and will be in 6.5.3.

I ran into this problem a long time ago. I simply disabled the c++ stuff,
as I don't use it.

As I see it, it is libpq-fe.h which should have:

#ifdef __cplusplus
extern "C" {
#endif

in the proper places.

It seems that cxx uses .hxx as the suffix for include files, so the
#includes would have to be #ifdef'ed appropriately. Also, cxx doesn't
recognize .cc as a c++ suffix, so you'll have to use the flag "-x cxx" or
it will think that the sources are plain c (which is probably the cause
of the second error you pointed at).

Nothing at all.

Exactly.
