nhmall 9bb96322a8 compile NetHack-3.7 without makedefs-generated .h files 
This evolves and hopefully eases the game-build requirements by
removing game-compile dependencies on any header files generated
by the makedefs utility, including:

date.h dependency and its inclusion is removed and comparable functionality
is produced at runtime via new file src/date.c.

pm.h dependency and its inclusion is removed and comparable functionality is
produced by moving the monster definitions from monst.c into new header
file called monsters.h and altering them slightly. The former pm.h header
file #define PM_ values are now replaced with appropriate emitted enum
entries during the compiler preprocessing.

onames.h dependency and	its inclusion is removed and comparable functionality
is produced by moving the object definitions from objects.c into new header
file called objects.h and altering them slightly. The former onames.h header
file #define values are now replaced with appropriate emitted enum entries
during the compiler preprocessing.

artilist.h has been slightly altered, and the former onames.h artifact-related
header file #define ART_ values are now replaced with appropriate emitted enum
entries during the compiler preprocessing.

makedefs can still produce date.h (makedefs -v), pm.h (makedefs -p), and
onames.h (makedefs -o) for reference purposes. They won't be used during
the compiler.

The other uses for makedefs remain. They are used to prepare external
file content that the game utilizes, not prerequisite code for the
compile:
    makedefs -d    (database)
    makedefs -r    (rumors)
    makedefs -h    (oracles)
    makedefs -s    (epitaphs, engravings, bogusmons)

date.c

Pull the code for date/time stamping from mdlib.c into date.c.
Set date.o to be dependent on source files, header files, and .o files
so that date.o is rebuilt from date.c when any of those changes, thus
ensuring an accurate date/time stamp. It also includes git sha
functionality formerly done by makedefs writing #define directives
into include/date.h. For unix it passes the git info on
the compile line for date.c (via sys/unix/hints/linux.2020, macOS.2020)

nethack --dumpenums (optional, but on by default)

Allow developer to obtain some internal enum values from NetHack
without having to resort to an external utility such as
makedefs.

Uncomment #define NODUMPENUMS in config.h to disable this.

The updates to sys/windows/Makefile.gcc have not been tested yet.

# newer makes predefine $(MAKE) to 'make' and do smarter processing of
# recursive make calls if $(MAKE) is used
# these makes allow $(MAKE) to be overridden by the environment if someone
# wants to (or has to) use something other than the standard make, so we do
# not want to unconditionally set $(MAKE) here
#
# unfortunately, some older makes do not predefine $(MAKE); if you have one of
# these, uncomment the following line
# (you will know that you have one if you get complaints about unable to
# execute things like 'foo.o')
# MAKE = make
# if you are using gcc as your compiler,
# uncomment the CC definition below if it's not in your environment
# CC = gcc
#
# For Bull DPX/2 systems at B.O.S. 2.0 or higher use the following:
#
# CC = gcc -ansi -D_BULL_SOURCE -D_XOPEN_SOURCE -D_POSIX_SOURCE
#
# If you are using GCC 2.2.2 or higher on a DPX/2, just use:
#
# CC = gcc -ansi
#
# For HP/UX 10.20 with GCC:
# CC = gcc -D_POSIX_SOURCE
#
# if your make doesn't define a default SHELL properly, you may need
# the line below (Atari users will need a bourne work-alike)
# SHELL = /bin/sh
