// -- INTEGER PROPERTIES -------------------------------------------------------

// The bit size of the integer type used to track values such as dimensions,
// strides, diagonal offsets. A value of 32 results in BLIS using 32-bit signed
// integers while 64 results in 64-bit integers. Any other value results in use
// of the C99 type "long int". Note that this ONLY affects integers used
// internally within BLIS as well as those exposed in the native BLAS-like BLIS
// interface.

// -- FLOATING-POINT PROPERTIES ------------------------------------------------

// Enable use of built-in C99 "float complex" and "double complex" types and
// associated overloaded operations and functions? Disabling results in
// scomplex and dcomplex being defined in terms of simple structs.
// NOTE: AVOID USING THIS FEATURE. IT IS PROBABLY BROKEN.

// -- MULTITHREADING -----------------------------------------------------------

// Enable multithreading via POSIX threads.

  // No additional definitions needed.
#else
  // Default behavior is disabled.

// Enable the CBLAS compatibility layer?
// NOTE: Enabling CBLAS will automatically enable the BLAS compatibility layer
// regardless of whether or not it was explicitly enabled above. Furthermore,
// the CBLAS compatibility layer will use the integer type size definition
// specified above when defining the size of its own integers (regardless of
// whether the BLAS layer was enabled directly or indirectly).
