[svn-r10913] Purpose: Work Around A Compiler Bug
Description: PGCC compiler on mir(AMD Opeteron) has a bug for optimization,
causing the multi driver test to fail. The compiler handles a macro in this
file incorrectly.
Solution: Slightly change the definition of this macro to avoid the problem
temporarily.
Platforms tested: h5committest, optimization and debug on mir.
