 * This header file contains dependencies to be *ONLY* used by the embedded or
 * extesion Python/C routines. These are typically found in src/lib/Libpython.
 *
 * Always include this header file within #ifdef PYTHON
 *
 * IMPORTANT:
 *   Under no circumstance this header file should be included by sources out-
 *   side the src/lib/Libpython directory. Extranlize any needed functionalities
 *   provided by this routine using generic pointers and place them in <pbs_python.h>.
 *
 *   The motivation for doing this is care has been taken so that the actual python
 *   build environment CPPFLAGS and CFLAGS are passed to the compiler that acts on the
 *   source files that include this header file. There will be situations where this
 *   compiler flags could break or spit out warnings if it is passed to the whole build
 *   environment.
