/* Configuration file for SuiteSparse: a Suite of Sparse matrix packages
 * (AMD, COLAMD, CCOLAMD, CAMD, CHOLMOD, UMFPACK, CXSparse, and others).
 *
 * SuiteSparse_config.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 SuiteSparse_config.mk:
 *
 * CFLAGS = -O -D'SuiteSparse_long=long long' \
 *  -D'SuiteSparse_long_max=9223372036854775801' -D'SuiteSparse_long_idd="lld"'
 *
 * This file defines SuiteSparse_long as either long (on all but _WIN64) or
 * __int64 on Windows 64.  The intent is that a SuiteSparse_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.
 *

/* 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 contains the following packages:
 *
 *  SuiteSparse_config version 4.2.1 (version always the same as SuiteSparse)
 *  AMD             version 2.3.1
 *  BTF             version 1.2.0
 *  CAMD            version 2.3.1
 *  CCOLAMD         version 2.8.0
 *  CHOLMOD         version 2.1.2
 *  COLAMD          version 2.8.0
 *  CSparse         version 3.1.2
 *  CXSparse        version 3.1.2
 *  KLU             version 1.2.1
 *  LDL             version 2.1.0
 *  RBio            version 2.1.1
 *  SPQR            version 1.3.1 (full name is SuiteSparseQR)
 *  UMFPACK         version 5.6.2
