* event-top.c (async_stop_sig) [HAVE_SIGPROCMASK]: Some
gratuitious whitespace changes. [!HAVE_SIGPROCMASK]: Call sigsetmask if HAVE_SIGSETMASK is defined. * top.c: Remove redundant logic to define HAVE_SIGSETMASK. (sigsetmask) Don't define macro. (stop_sig) [HAVE_SIGPROCMASK]: Add bit of code snatched from async_stop_sig from event-top.c. [!HAVE_SIGPROCMASK]: Call sigsetmask if HAVE_SIGSETMASK is defined. * configure.in (AC_CHECK_FUNCS): Put functions in alphabetical order. Add sigsetmask. (AC_FUNC_VFORK, AC_FUNC_ALLOCA): Reorder such that they're in alphabetical order. * config/xm-aix4.h, config/alpha/xm-alphalinux.h, config/i386/xm-cygwin.h, config/rs6000/xm-rs6000.h (HAVE_SIGSETMASK): Remove. * aclocal.m4, config.in, configure
