[svn-r7096] Purpose:
Bug fix
Description:
Aligned data is not being detected by type conversion routines correctly
on some Crays, causing corrupted data during I/O.
Solution:
Add extra checking for strange pointer behavior on Crays.
Platforms tested:
FreeBSD 4.8 (sleipnir)
h5committest
Cray SV1 (wind)
Cray T3E (hubble)
Cray T90 (gypsy)
