[svn-r4241] Purpose:
    Code Cleanup/Bug Fixes
Description:
    Raymond's last fix corrected the problem with eirene, but there were still
    a number of warnings, etc. during compiles.
Solution:
    Clean up the warnings, neaten up the code a little and change a few hsize_t's
    into size_t's that were missed in my previous sweep through the code.
Platforms tested:
    Linux 2.2 (eirene)
