/**
  MD5 implementation from Internet Standard RFC1321.

  This code is taken directly from:

      http://www.faqs.org/rfcs/rfc1321.html

  and is a straight cut-and-paste apart from the moving of the global.h
  header into this file, and the addition of the extern "C" braces.

  Note that glibc versions contain MD5 but do not expose it, so it is not
  possible to link to libcrypt and call the MD5 routines.

  Unlike glibc, dietlibc and uClibc both expose MD5.  When building
  Qtopia for these systems, this file may be removed from the build.
