// * GIVARO_HAVE_ANSI_NAMESPACE:
//   value: defined/undefined
//   purpose: define it in order to use name space in place of prefix
// * GIVARO_HAVE_ANSI_SPECIALIZED:
//   value: defined/undefined
//   purpose: define it in order to use ANSI declaration for specialization
//   of template functions.
// * GIVARO_HAVE_ANSI_EXCEPTION:
//   value: defined/undefined
//   purpose: define it in order to use ANSI exception classes hierarchy
//   as based classes for exceptions.
// * GIVARO_HAVE_ANSI_LIBRARY:
//   value: defined/undefined
//   purpose: define it in order to use ANSI library utilities (except for
//   container) as allocation without throwing exception, new str stream,
//   std header files...
// * GIVARO_HAVE_LBLAS:
//   value: defined/undefined
//   purpose: define it in order to use blas numerical library for some operations
//   as floating point matrice operations.
// * GIVARO_HAVE_TYPENAME:
//   value: defined/undefined
//   purpose: define it if the C++ compiler have typename keyword.
// * GIVARO_HAVE_LONG_LONG:
//   value: defined/undefined
//   purpose: define it if the C++ compiler have long long definition.
// * GIVARO_ASSERT_MACRO:
//   value: defined/undefined
//   purpose: expand additional code for assertion.
// * GIVARO_DEBUG:
//   value: defined/undefined
//   purpose: expand additional code for verification and debuging.
// * GIVARO_DEBUG_LEVEL:
//   value: integer > 0
//   purpose: <to be defined>
