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

annotate lib/signal.in.h @ 11424:2b94c0e7849d

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.
