Improvement
Description:
Removed "-D__GNUC__" which was a patch for previous version.
It is no longer needed.
Also moved the debug flags "-w2 and -Wall" to DEBUG_CXXFLAGS
so that they are used for debug mode only.
Also adjust CXXFLAGS setting so that -std=c99 is added only
if user has not preset CXXFLAGS. This allows users the option
of not using it.
Platforms tested:
Tested in tg-NCSA only since that is the only ia64 platform
around.
