  signal.h: always support 'volatile sig_atomic_t'
  
  * m4/signal_h.m4 (gl_SIGNAL_H): Check for AIX limitation.
  (gl_SIGNAL_H_DEFAULTS): Add a default.
  * modules/signal (Makefile.am): Substitute if needed.
  * lib/signal.in.h (sig_atomic_t): Redefine if needed, so that
  users can blindly add volatile.
  * doc/posix-headers/signal.texi (signal.h): Document it.
