+*=============================================================================
+*
+*  This version of wcstrig.h is based on the version in wcslib-2.9, but has
+*  been modified in the following ways by the Starlink project (e-mail:
+*  ussc@star.rl.ac.uk):
+*     -  Support for non-ANSI C prototypes removed
+*     -  Changed the name of the WCSLIB_TRIG macro to WCSLIB_TRIG_INCLUDED
+*     -  Changed names of degrees trig functions to avoid clashes with
+*        wcslib.
