/* This file has been modified for the Matrix package for R.  The SPQR
 * package requires the UF_long versions of other SuiteSparse
 * packages. On 32-bit systems these would be 32-bit ints but on
 * 64-bit systems these would be 64-bit ints.  R does not have a
 * native 64-bit int type.  To provide compatibility with the R
 * storage types and to allow use of SPQR without requiring both the
 * INT and the LONG versions to be compiled, we redefine UF_long to be
 * an int.  This is against the spirit of the documentation included
 * below but allows for only one version of the SparseSuite libraries
 * to be compiled and linked. Having a version of sparse matrices with
 * 64-bit integers in the compiled code does not make sense because
 * these cannot at present be represented as R objects (well, without
 * trickery like representing the i, j and p slots as doubles).

/* 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.

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

 * version of SuiteSparse, with another package from another version of
 * SuiteSparse, may or may not work.
