other. Ensure headers in include/ can be included in any order
(except for econfig-spec.h, which is special). New header types.h to
help avoid inclusion cycles. Sort include directives. Remove some
superflous includes.
files ship.config, plane.config, land.config, nuke.config.
(empfile): Declare the new config files.
(install, installdirs): Install them.
(builtins): New make variable.
Useless, remove. Users changed to check lchr's sentinel, because
that's clearer than comparing the index to N_MAXLAND or sizeof(lchr) /
sizeof(*lchr).
(lchr): Change sentinel's l_name to NULL.
be skipped or stored in arrays of size I_MAX. I_NONE's int equivalent
becomes -1 by this patch, so all array indices of type i_type have been
checked not to use I_NONE as index. This change reduces the size of the
arrays stored in files.
capacities to straight arrays. Users now subscript the array instead
of calling vl_find() or walking the variable data structure.
(mchr, lchr): Initializers adapted.
(vl_find): No longer used. Remove file.
ETUS is just the default for etu_per_update. Deities don't change
ETUS, they change etu_per_update by editing econfig. This nonsense
dates back at least to chainsaw 3.31, where it was just as broken as
now. Replace ETUS by 60 and simplify.
