According to Bruno Haible on 6/22/2008 1:58 PM:
| I don't understand the "Due to autoconf conventions". We are not using
| HAVE_SIGACTION as a #define in config.h. We are using it as a shell
variable.
| This shell variable is not set by either AC_REPLACE_FUNCS([sigaction])
| nor by AC_CHECK_TYPE(...). So there is no conflict.

I see your point.  AC_REPLACE_FUNCS([sigaction]) indeed sets the config.h
preprocessor variable HAVE_SIGACTION, and I omitted
AC_CHECK_TYPE([sigaction]) because it would also produce HAVE_SIGACTION;
but in config.h.in, we used only @HAVE_SIGACTION@, which is set independently.

Fine.
