[svn-r7684] Purpose:
Bug fix Description: Reduce optimization level from -O3 to -O for gcc 3.*, since it seems to be generating bad code for the atomic type conversions now... Platforms tested: FreeBSD 4.9 (sleipnir) Linux 2.4 (eirene, verbena) h5committest not necessary, this is a GNU-only change.
