-processor in collaboration with the University of California at Berkeley,
-overseen by Profs. Nelson Morgan and John Wawrzynek. More information
-is available through the Web page `http://HTTP.CS.Berkeley.EDU/~jhauser/

-Derivative works are acceptable, even for commercial purposes, so long as
-(1) they include prominent notice that the work is derivative, and (2) they
-include prominent notice akin to these four paragraphs for those parts of

-The macro `FLOATX80' must be defined to enable the extended double-precision
-floating-point format `floatx80'. If this macro is not defined, the
-`floatx80' type will not be defined, and none of the functions that either
-input or output the `floatx80' type will be defined. The same applies to
-the `FLOAT128' macro and the quadruple-precision format `float128'.
