Debugging, floating point type and parameter definitions.
In optimized code with NDEBUG defined, only VERB_INFO1, VERB_INFO2, and VERB_INFO3 are set. If NDEBUG is not defined, the code within #TRACE is used. If SOPLEX_DEBUG is defined, the code within VERB_DEBUG is also used.
If WITH_LONG_DOUBLE is defined, all Real numbers are of type long double instead of just double.

| #define SOPLEX_ASSERT_WARN | ( | prefix, | |
| expr | |||
| ) | ( assert( expr ) ) |
Macro to turn some assertions into warnings.
If both NDEBUG and WITH_WARNINGS are defined then the failed assertion is converted to a warning. In all other cases this macro is equivalent to assert().
| prefix | Short string for grepping in source code. |
| expr | Expression that must be satisfied. |

Prints/Executes stream with verbosity level verbosity, resetting the old verbosity level afterwards. Usually the parameter stream prints something out. This is an internal define used by SPX_MSG_ERROR, SPX_MSG_WARNING, etc.
