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