2092 * trans-intrinsic.c (gfc_conv_intrinsic_array_transfer): Has
2093 been absorbed into gfc_conv_intrinsic_transfer. All
2094 references to it in trans-intrinsic.c have been changed

2124 * resolve.c (check_host_association): Use the symtree name to
2125 search for a potential contained procedure, since this is the

2131 * interface.c (gfc_procedure_use): Don't warn about functions

2165 2009-01-04 Mikael Morin <mikael.morin@tele2.fr>
2168 * ChangeLog-2008: Fix function name.
2171 * dependency.c (gfc_check_argument_var_dependency):
2172 Move the check for pointerness inside the if block
2173 so that it doesn't affect the return value.
2176 * trans-stmt.c (gfc_trans_call):
2177 Add the dependency code after the loop bounds calculation one.
