  /* Configuration file for SuiteSparse: a Suite of Sparse matrix packages
   * (AMD, COLAMD, CCOLAMD, CAMD, CHOLMOD, UMFPACK, CXSparse, and others).
   *
   * UFconfig.h provides the definition of the long integer.  On most systems,
   * a C program can be compiled in LP64 mode, in which long's and pointers are
   * both 64-bits, and int's are 32-bits.  Windows 64, however, uses the LLP64
   * model, in which int's and long's are 32-bits, and long long's and pointers
   * are 64-bits.
   *
   * SuiteSparse packages that include long integer versions are
   * intended for the LP64 mode.  However, as a workaround for Windows 64
   * (and perhaps other systems), the long integer can be redefined.
   *
   * If _WIN64 is defined, then the __int64 type is used instead of long.
   *
   * The long integer can also be defined at compile time.  For example, this
   * could be added to UFconfig.mk:
   *
   * CFLAGS = -O -D'UF_long=long long' -D'UF_long_max=9223372036854775801' \
   *   -D'UF_long_id="%lld"'
   *
   * This file defines UF_long as either long (on all but _WIN64) or
   * __int64 on Windows 64.  The intent is that a UF_long is always a 64-bit
   * integer in a 64-bit code.  ptrdiff_t might be a better choice than long;
   * it is always the same size as a pointer.
   *
   * This file also defines the SUITESPARSE_VERSION and related definitions.
   *

   * apply to this file or to the UFconfig directory.  Author: Timothy A. Davis.

  /* SuiteSparse is not a package itself, but a collection of packages, some of

   * collection itself.  The versions of packages within each version of
   * SuiteSparse are meant to work together.  Combining one packge from one
   * version of SuiteSparse, with another package from another version of
   * SuiteSparse, may or may not work.
   *
   * SuiteSparse Version 3.0.0 contains the following packages:
   *
   *  AMD		    version 2.2.0
   *  CAMD	    version 2.2.0
   *  COLAMD	    version 2.7.0
   *  CCOLAMD	    version 2.7.0
