 ***************************************************************************
 *
 *  Many compilers provide a structure named "exception" in math.h, used to
 *  report errors from a floating point unit.  Some Microsoft compilers also
 *  #define complex as a synonym for a structure named _complex.  To prevent
 *  collisions with the Standard Library exception and complex classes, this
 *  header causes the old exception class to be renamed "math_exception" and
 *  removes the Microsoft complex symbol.
 *
 *  If you want to use math.h in conjunction with the Rogue Wave Standard
 *  library, always #include <rw/math.h> rather than <math.h>!
