+*   Test of the C wrapper for the DateTimePatternGenerator.
+*   Calls each C API function and exercises code paths in the wrapper,
+*   but the full functionality is tested in the C++ intltest.
+*
+*   One item to note: C API functions which return a const UChar *
+*   should return a NUL-terminated string.
+*   (The C++ implementation needs to use getTerminatedBuffer()
+*   on UnicodeString objects which end up being returned this way.)
