2606 * trans-intrinsic.c (gfc_conv_intrinsic_array_transfer): Has
2607 been absorbed into gfc_conv_intrinsic_transfer. All
2608 references to it in trans-intrinsic.c have been changed

2638 * resolve.c (check_host_association): Use the symtree name to
2639 search for a potential contained procedure, since this is the
2640 name by which it would be referenced.
2642 2009-01-06 Thomas Koenig <tkoenig@gcc.gnu.org>
2645 * interface.c (gfc_procedure_use): Don't warn about functions

2677 * resolve.c (check_host_association): Return if above is set.
2679 2009-01-04 Mikael Morin <mikael.morin@tele2.fr>
2682 * ChangeLog-2008: Fix function name.
2685 * dependency.c (gfc_check_argument_var_dependency):
2686 Move the check for pointerness inside the if block
2687 so that it doesn't affect the return value.
2690 * trans-stmt.c (gfc_trans_call):
2691 Add the dependency code after the loop bounds calculation one.
