vchoi_fork

[svn-r6721] Purpose:
bug fix

Description:
in the close strong case in H5F_close there was a do..while loop
that executed when nfiles==0, calling malloc(0)
this was causing a failure in the close call in Code Warrior, that returns 0
in the call pt=malloc(0)

Solution:
replaced with a while loop (checks the condition before executing)

Platforms tested:
code warrior, linux

Misc. update:
