+dnl If the configure.ac contains a definition of the gl_THREADLIB_DEFAULT_NO

+dnl default is 'no', otherwise it is system dependent. In both cases, the user
+dnl can change the choice through the options --enable-threads=choice or

 dnl Defines at most one of the macros USE_POSIX_THREADS, USE_SOLARIS_THREADS,
 dnl USE_PTH_THREADS, USE_WIN32_THREADS
