* configure.ac (sys_siglist): Look for its decl in <signal.h>. Otherwise, it's not found in either Fedora 17 or Solaris 11. * src/sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's defined as a macro, as is done in Solaris. (sys_siglist_entries): New macro. (save_strsignal): Use it. * src/syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
