Clean up the preprocessing associated with the
loadable symbol stuff.
Base it on new LOADSYMSETS, rather than on the
previously existing ASCIIGRAPH preprocessor define.
- tile2x11 would not build because drawing.c now depended on strcmpi which
was (via STRNCMPI not being defined) defined to strncmpi which is
implemented in hacklib.c which needs panic which is defined in... I gave up
on tracking down all the loose ends and changed the strcmpi to strcmp,
which means the handling is case sensitive, but it avoids a bunch of
changes to the way the util/Makefile.
- the symhandling changes introduced a chicken and the egg problem for
ASCIIGRAPH on Unix platforms, which was getting the defn from tcap.h but
that does not get included earlier enough nor often enough. I added a defn
to unixconf.h to mimic ntconf.h, since ASCIIGRAPH is normally defined on Unix.
- options.c included an unused decl for a function named graphics_opts
- Unix Makefile was not installing "symbols". I'm assuming this isn't
supposed to get the DLB treatment.
This is an initial round of SAFERHANGUP hangup changes. It introduces
SAFERHANGUP, provides the core framework, and enables it for UNIX.
Window-port changes are provided for win/tty, win/X11 and win/gnome. Qt
changes should be forthcoming after having Warwick look at them.
window.doc is updated so windowport maintainers have an clue what needs to
be done to support SAFERHANGUP.
Finally got around to installing OpenBSD (rev 3.3) in a vmware partition.
Found that several #if BSD's were inappropriate for modern BSD's. Haven't
installed FreeBSD or NetBSD, but based on reading their man pages,
these changes are needed there too. Mostly due to POSIX time() signature.
Switch the default Linux build behavior to use random instead of lrand48,
since lrand48 exhibits some obviously non-random behavior. random() has
been in glibc for a long time. Even if no other changes are made to
nethack's random number generator, this will improve the Linux behavior.
