Should Cygwin PostgreSQL contain all header files?

In the process of helping someone build PoPy

    http://sourceforge.net/projects/popy

under Cygwin, I have realized that my Cygwin PostgreSQL distribution
may be missing some header files.

Please see the following for details:

    http://www.cygwin.com/ml/cygwin/2001-06/msg00434.html

The bottom line is should I be using

    make -C src/include install-all-headers

instead of

    make -C src/include install

or is PoPy's use of non-client-side headers incorrect?

BTW, it appears that others (i.e., non-Cygwin users) have noticed this
issue too:

Thanks,
