Current patch: http://gcc.gnu.org/ml/fortran/2010-09/msg00303.html

I followed the suggestion of Mikael at 
http://gcc.gnu.org/ml/fortran/2010-09/msg00198.html to moved the 
function from trans-decl.c to gfc_get_function_type in trans-types.

And I use -fno-inline for the test Cray test case to avoid wrong-code 
issues due to the invalid aliasing in the test case (which is needed to 
check the result).
