Quincey Koziol 324cd9d1e2 [svn-r7616] Purpose: 
Code cleanup

Description:
    Change field member count and indices for compound and enumerated types from
'int' to 'unsigned' to better reflect actual use.

    Cleaned up a few other minor compiler warnings, etc.

Platforms tested:
    FreeBSD 4.9 (sleipnir)
    Linux 2.4 (verbena)
    too minor to require h5committest
