[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)
