nhmall 69600c3f38 add an optional deploy-to-dosbox target for msdos cross-compile
The WANT_DEBUG=1 will cause the cross-compile to include line
number information in the NetHack executable, useful for
backtraces and gdb debugging sessions.

How a developer can use the optional deploy-to-dosbox target:
    make CROSS_TO_MSDOS=1 WANT_DEBUG=1 dosbox=/mnt/c/dosbox deploy-to-dosbox

where dosbox= points to the directory which will be mounted for
your drive in dosbox

THe deploy-to-dosbox recipe ensures that a target copy of gdb.exe
ends up alongside nethack.exe at the target, including:
  - placing the source code that gdb requires on the target
    in the nhsrc subfolder.
  - an nhgdb.bat that supplies the right switches to gdb
    for locating the NetHack sources.

This README provides the instructions for building the unofficial Mac
binaries using the Apple provided developer IDE named XCode.

Establish a developer team in XCode
===================================

Your first step should be to establish a developer team within XCode.
Launch XCode and open the preferences dialog (XCode Menu->Preferences).
Select the "Accounts" tab.  Add an account (usually this should just be
your apple ID account you used to setup the Mac).  After adding the account,
select the account and then add a team (usually this will be just a
personal team for Mac Development).

Obtain your developer team identifier
=====================================

Your DEVELOPMENT_TEAM can be found by opening Keychain Access
(found by Finder->Applications->Utilities).  Click on "My Certificates".
Look for your "Mac Developer" certificate.  Right click on
the certificate to open a dialog that shows certificate details.
Look for "Organizational Unit" among the details.  This ten digit value
is your development team identifier.

Create XCodeLocal.xcconfig file
===============================

Now you need to create the XCodeLocal.xcconfig file that will be used by
XCode to get your development team identifier.  Create the file in
sys/unix and add a single line such as:
DEVELOPMENT_TEAM = XXXXXXXXXX

Where XXXXXXXXXX is replaced with your development team identifier.

Open the project and build
==========================

In XCode open the project file sys/unix/NetHack.xcodeproj, select
the product NetHack and build.  The build results are placed in
~/nethackdir.
