Anasazi: Build error with Scalar=complex<float> enabled

[mhoemmen]

Bug Report

@trilinos/anasazi

Description

anasazi/src/AnasaziMVOpTester.hpp has code like this:

     ScalarType alpha = 0.5 * SCT::one(),
                 beta = 0.33 * SCT::one();

SCT is Teuchos::ScalarTraits<Scalar>. When Scalar is complex<float>, this code does not compile, because operator*(double, complex<float>) does not exist. The fix is to cast the constants 0.5 and 0.33 to MagType (which is float in this case):

     ScalarType alpha = MagType(0.5) * SCT::one();
     ScalarType beta = MagType(0.33) * SCT::one();

Steps to Reproduce

1. Set Trilinos_ENABLE_COMPLEX_FLOAT:BOOL=ON.
2. Build Trilinos (I'm using Mac Clang).
