* This file is needed for systems, that do not provide XDR support
* in their system libraries. It was written for windows, but will
* most probably work on other platforms too. better make sure you
* test that the xtc files produced are ok before using it.
*
* It is also needed on BG/L, BG/P and Cray XT3/XT4/XT5 as we don't
* have XDR support in the lightweight kernel runtimes either.
