Quincey Koziol c97fddc786 [svn-r8892] Purpose: 
Code cleanup

Description:
    Clean up a bunch of warnings and bring new code better inline with current
library coding practice.

Platforms tested:
    FreeBSD 4.10 (sleipnir) w/parallel
    Too minor to require h5committest

Misc. update:
2004-07-16 15:48:40 -05:00
