This commit changes the underlying opal complex datatypes to match the C99 types: float _Complex, double _Complex, and long double _Complex. The fortran and C++ types now are aliases to these basic types instead of structure types. The operators in ompi/mca/op/base now work on only the C99 types and the fortran types use these operators if the fortran type matches a C complex type (this should almost always be the case.) C99 is not is use in both the datatype and operator code and should make the code both cleaner and much less fragile. This commit was SVN r29193.
