[svn-r1083] Purpose:
Bug fix Problem: Currently, when --enable_preduction --disable-debug modes are selected during configure, the optimization level scheduled is -O (-O2). Unfortunately, this level of optimization relaxes too much the alignments necesary for the building, and testing of the hdf5 library. Solution: Lower the level of optimiztion to -O1. This still maintains required alignments. Platform tested: Irix6.5(fuga)
