/* This is really kludgy but not sure what else to do at this point.
   It appears that if PACE_HAS_POSIX is not defined (i.e., no #define
   at all of any kind) and the same goes for PACE_VXWORKS then in
   pace/config/config.h #if PACE_HAS_POSIX == PACE_LYNXOS will evaluate
   to true. I am assuming both get default values of 0.

   PACE_WIN32 should be defined as 0 though because pace/config/utility.h
   checks it.
