G95 currently allows different type kinds (ie. double or single precision) as
an extension, but not different types. It could easily be modified to accept
different types. I've no idea how easy/hard it would be to get g77 to do
something similar.
As this code is non-portable and techincally illegal a warning is issued. This
becomes an error with -pedantic.
