In 4.4, the following changed (see http://gcc.gnu.org/gcc-4.4/changes.html):

"GNU Fortran now employs libcpp directly instead of using cc1 as an 
external preprocessor. The  -cpp option was added to allow manual 
invocation of the preprocessor without relying on filename extensions."

Kind regards,
