I'd be happy for answers for more than one compiler, of course -- I'd guess that e.g. pathscale might have a greater capacity than e.g. gfortran than g77 legacy...
PathScale also supports -mcmodel=medium for large arrays, and I think gcc originated that flag name, so I would guess that gfortran supports it as well.
pathf95 also supports the -i8 flag. If you need a math library to support large arrays with i8-type indices, when you download the PathScale version of ACML from AMD, you can choose the "PathScale 64-bit Int64" version. I would guess that Intel's MKL also has a version that supports 64bit integer arrays.
