  28 define Package/libpthread-stubs/description
  29 This library provides weak aliases for pthread functions not provided in libc
  30 or otherwise available by default.  Libraries like libxcb rely on pthread
  31 stubs to use pthreads optionally, becoming thread-safe when linked to
  32 libpthread, while avoiding any performance hit when running single-threaded.
  33 libpthread-stubs supports this behavior even on platforms which do not supply
  34 all the necessary pthread stubs.  On platforms which already supply all the
  35 necessary pthread stubs, this package ships only the pkg-config file
  36 pthread-stubs.pc, to allow libraries to unconditionally express a dependency
  37 on pthread-stubs and still obtain correct behavior.
