Autoconf was failing to detect install-sh at the top level and needed
some explicit directions. It also wants config.guess and config.sub to
be provided too.
A few other macros have also been updated.
When attempting to buy an unaffordable object, messages were often of
the form "You can't afford that a scroll of hold monster !", because
the object description (stored in curpurch) was the same text used in
inventory displays.
This has been worked around by inspecting the contents of curpurch and
using different message templates.
do_zap() dereferenced a struct object pointer while ignoring the result
of a NULL check. XRogue had the same problem, though triggering it was
unlikely, since XRogue does not include a magic missile spell.

pick_spell() attempted to capitalize type by overwriting the first
character, changing it back later. All calls of pick_spell passed a
string literal as type, and string literals should be considered
immutable.
This has been fixed by using a separate variable for the capitalized
first character. XRogue already has a similar fix.

Some code for determining the score file location assumed that PATH_MAX
would be less than 1024, which cannot be guaranteed.
Advanced Rogue 5 and 7, and XRogue, have had the buffers for the file
name enlarged. UltraRogue never called the functions, so the code has
been deleted instead.
The variables file_name, score_file, and home are no longer overwritten
with the values stored in the save file. Those values could be
inaccurate if the files have been moved or configuration has changed.
Constants K_ARROW etc., for causes of death other than monsters, are in
the 240-255 range. They were often passed to functions taking char,
which is usually signed, making the values out of range.
The function declarations have been changed to unsigned char, which is
also the type used by the scoreboard code.
There should only be two changes in behavior:
arogue7/fight.c, arogue7/fight.c: a to-hit bonus is now correctly
applied to characters who are not monks instead of monks who are not
empty-handed.
urogue/fight.c: fixed an interaction with the "debug" macro that could
cause the wrong message to be displayed.
The next_obj field is a pointer which the top item in a stack uses to
keep a list of the other items. When removing an item from the stack,
rem_obj() failed to set next_obj to NULL, which can cause items in
monster inventory to point to items earlier in the inventory list.
That causes infinite co-recursion when saving or restoring.
Inventory letters are based on "identifiers" stored in objects' o_ident
field. Identifiers are allocated by get_ident(), which keeps a list of
objects that have them, to avoid giving the same identifier to multiple
objects.
The list is not stored in the savefile, so after restore, get_ident()
was not aware of existing identifiers. This resulted in picked-up
objects having the same inventory letters as objects restored from the
file.
The restore code now adds all objects with identifiers to the list.
Some games' implementation of md_hasclreol() poked around in ncurses
internals, which does not work for some ncurses build configuration.
Most games did not actually call md_hasclreol(), so it was removed.
There is a standard terminfo function which can retrieve the value of
the clr_eol capability, so this was used for rogue5.
Functions in memory.c tracked and instrumented memory allocation. This
mechanism logged information to a text file and also added a 16KB guard
area to every allocation. Neither of these are desirable in a multi-
user environment, so the whole memory tracking subsystem has been
disabled.
The behavior can be enabled with a configure flag, but it would be a
better idea to use Valgrind to deal with memory bugs.
In md_shellescape(), signal handlers for SIGINT and SIGQUIT were saved
and restored, but exchanged in the process. This was fixed in the
other games by commit 600873555ec0.
Deleting md_shellescape() might have been a better fix. It is
apparently unused.
The function wrapped the standard putchar(), doing nothing beside
discarding the return value. That could cause problems with tputs(),
which expects an int to be returned.
In some games, restore() passes the result of ctime() to mvprintw() or
some other variadic message-formatting function. If ctime() has not
been declared properly, its return type is inferred to be int instead
of char *. This does not cause a warning because the compiler does not
know the correct type of variadic arguments.
On platforms where ints and pointers are not the same size, this can,
probably depending on alignment, result in a segfault that is not easy
to trace.
Including time.h fixes the problem. Some games manually declared
ctime() and avoided the bug. These declarations have also been
replaced with the include.
Marking non-magic items caused segfaults because item_color was set to
NULL. item_type could also be used as an out-of-bounds index. These
problems have been fixed by only using these variables when the mark
argument is false, in which case they are properly initialized.
A fall-through case statement was also fixed.
It is possible for getpwuid() to return NULL. Such a failure will no
longer cause a segfault. However, the call to getpwuid() may normally
not be reachable.
