   This is a heavily stripped down version of the GNU Pth
   (GNU Portable Threads) package. It was automatically
   generated by a call to ``make striptease'' from within
   a full-sized GNU Pth source tree. DO NOT EDIT ANYTHING
   HERE. CHANGES WILL BE LOST IF AN UPDATED STRIPPED DOWN
   VERSION IS IMPORTED NEXT TIME TO THIS AREA. For the
   complete source go to http://www.gnu.org/software/pth/.
