2611 * trans-intrinsic.c (gfc_conv_intrinsic_array_transfer): Has
2612 been absorbed into gfc_conv_intrinsic_transfer. All
2613 references to it in trans-intrinsic.c have been changed

2615 character transfer, when the source is shorter than the

2643 * resolve.c (check_host_association): Use the symtree name to
2644 search for a potential contained procedure, since this is the

2684 2009-01-04 Mikael Morin <mikael.morin@tele2.fr>
2687 * ChangeLog-2008: Fix function name.
2690 * dependency.c (gfc_check_argument_var_dependency):
2691 Move the check for pointerness inside the if block
2692 so that it doesn't affect the return value.
