Update from version 2.0.0.21 to 2.0.0.21nb1.

Pkgsrc changes:
 o For the benefit of 64-bit strict alignment archs using gcc, such
   as NetBSD/sparc64, ensure that the specially crafted double values
   are properly aligned.  Thanks to martin@ for pointing to the problem.

   This should stop regxpcom from dropping core on NetBSD/sparc64.
