[Users] Compiling ET Using PGI

[Erik Schnetter]

These warnings indicate that the symbol CCTK_REAL8 is not defined.
Most likely, something went wrong in the configure stage, and Cactus
didn't realize that CCTK_REAL8 should be "double".

Very old C allowed defining functions without specifying a result
type, and the function would then be assumed to return "int". The PGI
compiler still supports this, hence this is a warning, not an error.
