1998-11-11 Martin Baulig <martin@home-of-linux.org> * configure.in (--enable-debug): Define LIBGTOP_ENABLE_DEBUG if this parameter is given. (--enable-fatal-warnings): New parameter to make all warnings fatal; define `LIBGTOP_FATAL_WARNINGS' if given. * sysdeps/common/error.c (glibtop_error_r): Use abort () instead of exit () if LIBGTOP_ENABLE_DEBUG. (glibtop_error_io_r): Likewise. (glibtop_warn_r): Call abort () if LIBGTOP_FATAL_WARNINGS. (glibtop_warn_io_r): Likewise. [NOTE: To get a core dump of the libgtop_server, you need to remove all suid/sgid bits and invoke it as a priviledged user.]
