/* Simple fallback-include to enable thread-enabled exception support
   for libgcc, but with posix-interface to a default-dummy, so a posix
   library can optionally be linked in, which isn't possible if
   gthr-single.h is used.  No other use is supported; *DO NOT* think
   this gives you a valid pthread interface to use in your applications.  */
