[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)
