 * included code, as opposed to a separate library or object
 * dependency.  In the absence of portable "pragma weak" compiler
 * directives, this provides a simple workaround.
 *
 * Usage for a single compilation unit:
 *
 *  #include "pncompat/misc_funcs.inc"
 *
 * Usage for multiple combined compilation units: chose one to include
 * "pncompat/misc_funcs.inc" as above and in each other unit needing the
 * definitions use
 *
 *  #include "pncompat/misc_defs.h"
