Add qh_QHpointer defines to vcproj files
Add libqhullp to sln solution file

Updated version.  Checked into Perforce.

Create libqhullp.a with qh_QHpointer=1 for qhullcpp.dll, etc.
  gcc has halved the cost of qh_QHpointer by using more space
Add <time.h> to user.h for CLOCKS_PER_SEC
Move ostream<<QhullFacetList from inline to compiled.
  It tripped a double define error like the other classes.
Remove ptr_intT from qh_matchvertices.  Not needed.
Fix name of qh_QHpointer

Fixed type of tempstack and old_qhstat [amorilia]
Changed tabs to spaces

Removed no_strict_aliasing.
Renamed index to idx to avoid shadowing BSD strings.h [kwilliams]

g++ -O2 works OK with gcc 4.4.0
eg/q_test produced some problems to chase (see Changes.txt)
Passes qhulltest --all

Revert amorilia's datatyping of old_qhstat and tempstack (needs further review).

Fix spacing on output and remove blank line on error

Added project files for qhull programs
Changed qh_gethash to return an int
Changed qh_addhash to take an int

Updated citeseer references to  citeseerx doi =10.1.1.117.405
Changed copyright to C.B. Barber
Updated Register.txt to Qhull

Organized src/Changes.txt
Updated copyright dates
Fixed warnings from Kent William
Reviewing FIXUP
Add qhull-all.pro to build projects in order
Passed 127 tests.

Moved vector<> from base type of Coordinates to a field
Changes to Coordinates to match iterator and subtype guidelines
Add PointCoordinatesIterator
Split dynamic and static libs for qhull and qhullcpp
Move class objects after fields in .h files
Added more changes.txt
Changed version to 2009.0.1

Breaking change
  Renamed qhulllib to libqhull to match libqhull.a
  Keep rboxlib as is.  librbox does not scan and rbox is not a lib

Qhull and rbox build correctly under mingw with gcc 4.4.0.  Please
send email to bradb@shore.net if Qhull builds correctly with Linux
gcc 4.4.0 -O2.   With gcc 4.2 and 4.3 qset.c segfaulted due to an
optimization error.

user_eg3 is a demonstration of using Qhull C++ interface.

Qhulltest contains some failing testcases due to changes made for user_eg3.
Will be fixed soon.

qhull-qt reports an error because the link does not skip userprintf.c
in libqhull.a.  Also the dependencies between qhull-qt and libqhull.a
are handled incorrectly.

Includes QTest files for each class and user-eg3.c for demonstrating the interface.
See src/Changes.txt for change notes and to do.
