-**
-** Interface declarations and internal definitions for Skein hashing.
-**
-** Source code author: Doug Whiting, 2008.
-**
-** This algorithm and source code is released to the public domain.
-**
-***************************************************************************
-** 
-** The following compile-time switches may be defined to control some
-** tradeoffs between speed, code size, error checking, and security.
-**
-** The "default" note explains what happens when the switch is not defined.
-**
-**  SKEIN_DEBUG            -- make callouts from inside Skein code
-**                            to examine/display intermediate values.
-**                            [default: no callouts (no overhead)]
-**
-**  SKEIN_ERR_CHECK        -- how error checking is handled inside Skein
-**                            code. If not defined, most error checking 
-**                            is disabled (for performance). Otherwise, 
-**                            the switch value is interpreted as:
-**                                0: use assert()      to flag errors
-**                                1: return SKEIN_FAIL to flag errors
