<li>Report an error if qh_newhashtable, qh_setnew, or qh_memalloc overflows [X. Cheng].  Overflow may occur on 64-bit hosts.  Qhull uses 32-bit ints for identifiers, counts, and sizes.

Bug fixes
 - qh_new_qhull: Call qh_prepare_output if !outfile [A. Aldoma]
   No effect on qhull users since qh_prepare_output is always called.
 - Replace Qhull-go.pif with Qhull-go.lnk for Windows 7 64-bit [lots]
 - Error if qh_newhashtable, qh_setnew, or qh_memalloc overflows [X. Cheng]
   For example, 'rbox 64 D32' overflows hash table for qh_matchnewfacets
   Qhull uses 32-bit ints for identifiers, counts, and sizes. See "WARN64"
 - q_eg, q_test: change tail +3 to tail -n +3 [N. Dubray, M. Atzeri]
 - Qhull-go.bat: Changed 'cmd' to '%comspec%'

Build changes
 - Added src/libqhull/Makefile for simple gcc build of executables and lib
 - qhulltest.vcproj: Replaced full path to QT with $QTDIR (e.g., c:/qt/4.7.4)
 - Split userprintf_rbox.c from userprintf.c,
   Otherwise qhull brings in rboxlib and rbox brings in libqhull
 - Makefile: qhullx target must be after LIBQHULLS_OBJS
 - Makefile: Explicitly list rbox dependencies for qhullx target
 - MBorland: Fixed tabs
 - Placed $LIBQHULLS_OBJS in same order.  Frequently called ones together.
 - Update file lists for Make-config.sh [O. Lahaye]
 - CMakeLists: add README.txt,etc. to DOC_INSTALL_DIR [M. Atzeri]
 - Restored qhull.h-deprecated.
   qhull.h conflicts with Qhull.h on Windows systems [C. Abela]
 - make-config.sh: Add warning that it is out-of-date
 - Remove extra space in '#! /bin/sh' in q_eg, etc. [P. Cheeseman]

Source changes
 - libqhull.h: Added qh_True and qh_False for True/False [A. Mutzel]
   Did not remove or replace True/False since it is used everywhere
 - Moved error message from qh_argv_to_command to caller.  Avoids dependency.
 - user_eg3.c: Use '10 D2' as default rbox (e.g., 'user_eg3 rbox qhull d')
 - user.c, user_eg2.c: Add test of qh_qh as done in user_eg.c
 - q_test: Removed duplicate test of qhull C-0.02
