2102 * resolve.c (check_host_association): Use the symtree name to

2149 * dependency.c (gfc_check_argument_var_dependency):
2150 Move the check for pointerness inside the if block

2154 * trans-stmt.c (gfc_trans_call):
2155 Add the dependency code after the loop bounds calculation one.

2175 Support pointer-returning functions.
2177 2009-01-03 Daniel Franke <franke.daniel@gmail.com>
