Update
*** libcdd version (date) / changes ***

Version 094g (March 23, 2012) /
 - Thanks to both Anders Jensen and Mathieu Dutour
   a few memory leaks in cddlib.c and cddlp.c have been
   fixed.  Also, some patches sent by Jerry James have
   been applied.  These were for making the library
   shared and more compatible for C++ compilers.

Version 094f (February 7, 2008) /
 - Thanks to Sven Verdoolaege's fixes,
   the "configure" script now uses "gcc" as the default
   compiler, rather than "g++" in earlier releases,
   and the libraries can be linked properly with
   both C and C++ programs.

Version 094e (January 27, 2008) /
 - A bug of reporting a wrong (sign) certificate of
   an infeasible LP is fixed.  This bug reported by
   Charles Geyer, occurs if the exact GMP version of 
   the dd_LPSolve is used with minimization. A bug of
   reporting infeasibility of a feasible LP with 
   column non-full rank LP is fixed.  This bug was reported
   by Sven Verdoolaege.

Version 094d (February 12, 2007) /
 - A bug of reporting a wrong unbounded direction vector of
   a dual inconsistent LP is fixed.  This bug occurs only
   if the exact GMP version of the dd_LPSolve is used.
   For example, this error may occur in scdd_gmp.  This
   error was reported by Lars Schewe.

Version 094c (April 23, 2006) /
 - A bug for reading a rational number of length longer
   than 255 characters have been fixed. This was reported
   by Ruriko Yoshida. Now the longest
   number is controlled by dd_wordlenmax defined in
   cddtypes.h .  The longest line is also controlled by
   dd_linelenmax .  These are currently fixed to
   1024 and 4096.  Larger numbers and lines can be
   handled by modifying these numbers and recompilation.

Version 094b (August 25, 2005) /
 - A bug for the representation conversion, reported by
   Michal Kvasnica, was fixed.  The earlier 094* versions
   prematurely terminate the conversion when the number
   of rows is equal to the number of columns in the input.
   This means the earlier 094* do not compute correctly 
   for simplices, for example.

Version 094a (August 24, 2005) /
 - A bug of dd_LPSolve is fixed.  This bug, reported by
   Dima Pasechnik, due to a mishandling of cycling of LP
   algorithms, is fixed.

Version 094 (August 4, 2005) /
 - dd_MatrixCanonicalize has been added.  This reduces
   matrix M to a minimal representation by computing
   all implicit linearity rows and all redundant rows.
   It applies lexicographic sorting of rows to remove
   duplicates before applying redundancy removal.
   This function combines the two computations together
   in more efficient manner than before.
   See the new redcheck.c for its use.  Several basic
   operations for matrices have been added, such as
   dd_MatrixRowsRemove and dd_MatrixRowsRemove2.

   The representation conversion dd_DDMatrix2Poly now
   handles the empty H-polyhedra properly, by calling
   an LP-based emptiness checker before running the double 
   description algorithm.

   New functions finding specific points in H-polyhedra
   are added.  dd_ExistsRestrictedFace is a general inequality
   system solver with specified equations, inequalities and
   strict inequalities.   dd_FindRelativeInterior finds 
   a point in the relative interior of a polyhedron.

Log message:
Drop superfluous PKG_DESTDIR_SUPPORT, "user-destdir" is default these days.
Mark packages that don't or might probably not have staged installation.
