octave-lojdl/gnulib-hg: lib/signal.in.h annotate

annotate lib/signal.in.h @ 14686:e753ffb0501f

signal: Define sighandler_t. * lib/signal.in.h (sighandler_t): New type. * m4/signal_h.m4 (gl_SIGNAL_H): Require AC_USE_SYSTEM_EXTENSIONS. Test whether sighandler_t is defined. (gl_SIGNAL_H_DEFAULTS): Initialize HAVE_SIGHANDLER_T. * modules/signal (Depends-on): Add extensions. (Makefile.am): Substitute HAVE_SIGHANDLER_T. * doc/posix-headers/signal.texi: Mention the problem with sighandler_t. Suggested by Markus Steinborn <gnugv_maintainer@yahoo.de>.
