 /* Release notes:
    31 Jan 2001:
-      Added test case for is_convertible with UDT that brings out the
-      warning message bug with g++. Added a test for is_array
-      using a const array, and a test for is_convertible with
-      a user-defined implicit conversion. Changed signature
-      of main() so that this program will link under MSVC. (Jeremy Siek)
