Performance profiling showed that multiple strcmpi() calls were
occurring each and every time a character was going to the map.
This update:
- honors the WC_COLOR capability
- It allows a window-port to control individual color availability should the window-port wish to do so.
- Makes checking on the individual colors for the active window-port is a straightforward table lookup at the CLR_ offset.
iflags.use_color remains a master on/off switch for use of color, regardless of the capability
compiled into the game (default TRUE).
The has_color() routine, which is now a shared routine in src/windows.c, could likely be made
into a simple macro to eliminate the function call, but this update does not go that far.
This hits a lot of port files due to the window-port interface change, mostly cookie-cutter.
Another part of github issue 227. Casting a function pointer when
passing it to another function is iffy when lying about the return
type. tputs() expects a routine which returns int, so give it one.
Other xputc() usage is equivalent to putchar(), so define xputc()
with the same function signature as that has.
The tputs() declarations in system.h should probably be changed
(third argument is a function which takes an int rather than
unspecified parameters) but I've left them alone. I made that change
to tputs() in sys/share/tclib.c though.
NT and MSDOS changes are untested. tclib.c compiles ok with clang-
as-gcc on OSX but hasn't been tested with the port that uses it (VMS).

Because multiple window ports are supported on Windows
now, even in the same executable and selectable via
config file in some cases, some adjustments became
necessary. There will likely be some further refining
of this over the next day or two.
List of changes:
Move Windows startup from sys/share/pcmain.c and
into its own sys/winnt/windmain.c so that it can
be modified to fix some current breakage, and
allow altering the order of some things.
There is startup processing code that is common to
all of the Windows WindowPorts, but that startup
processing code needs to have no dependency on
any one of those WindowPorts.
Yet, during startup processing, some of the initialization
routines can end up calling NetHack functions that
expect an active Window port underneath, and if there
isn't one, routines like pline, impossible, panic can
end up invoking null function pointers.
Place a new file sys/share/safeproc.c, in which a complete
window port is available for early startup processing
purposes. It's WindowPort name field is set to
"safe-startup" just for reference. The prototypes in
include/winprocs.h require that SAFEPROCS be
Usage:
windowprocs = get_safe_procs(0);
initializes a set of winprocs function pointers that ensure
none of the function pointers are left null, but that's all it does.
windowprocs = get_safe_procs(1);
initializes a set of winprocs functions pointers that ensure
none of the function pointers are left null, but also
provides some basic output and input functionality using nothing
other than C stdio routines (no platform or OS specific code).
The conditional code related to WIN32 has been removed from
sys/share/pcmain.c
The code common to all of the Windows WindowPorts calls
get_safe_procs() almost immediately to ensure that
there is a set of WindowPort winprocs available.
Moved the code page 437 mapping table to winnt.c so that it could be
used in window and console clients.
Added check that fonts support unicode values we use from code page 437.
Use unicode to draw text if font supports it otherwise use ASCII.

Bug 123 Report 4030:
Minor thing I've noticed - if I quit the game, at the "Hit <Enter> to end."
prompt, if I close the window rather than pressing Enter, I get the following:
Bug 138 - #H4045:
"nethack -s" leads to "-s is not supported for the Graphical Interface".
That's wrong.
(The Graphical Interface comes with "nethackw".)
Make the variadic functions look more like ordinary code rather than
have the function opening brace be hidden inside the VA_DECL() macro.
That brace is still there, but VA_DECL() now needs to be followed by
a visible brace (which introduces a nested block rather than the
start of the funciton). VA_END() now provides a hidden closing brace
to end the nested block, and the existing closing brace still matches
the one in VA_DECL().
Sample usage:
void foo VA_DECL(int, arg) --macro expansion has a hidden opening brace
{ --new, explicit opening brace (actually introduces a nested block)
VA_START(bar);
...code for foo...
VA_END(); --expansion now provides a closing brace for the nested block
} --existing closing brace, still pairs with the hidden one in VA_DECL()
This should help if/when another round of reformatting ever takes place,
and also with editors or other tools that do brace/bracket/parenthesis
matching.
I had forgotten that there were variadic functions in sys/* and ended
up modifying a lot more files than intended. The majority of changes
to those just inserted a new '{' line so that revised VA_END()'s '}'
won't introduce a syntax error. A couple of them needed VA_END() moved
so that local variables wouldn't go out of scope too soon. Only the
Unix ones have been tested.
I'll push a formatting guide at some point. There may still be
outstanding changes, but please feel free to resolve those as you arrive
a them.
To the best of my knowledge, there is no changes to the actual code
content, but the formatter does have the occasional bug. If you run into
an issue, please fix it!

Adjust the code and the command line Makefile so that
you no longer have to choose whether to build the tty
version NetHack.exe, or the gui version NetHackW.exe.
Both will now be built in a single 'nmake install' pass.
