re PR fortran/34975 (Bogus error with USEing modules)
2008-01-30 Paul Thomas <pault@gcc.gnu.org>
PR fortran/34975
* symbol.c (gfc_delete_symtree, gfc_undo_symbols): Rename
delete_symtree to gfc_delete_symtree.
* gfortran.h : Add prototype for gfc_delete_symtree.
* module.c (load_generic_interfaces): Transfer symbol to a
unique symtree and delete old symtree, instead of renaming.
(read_module): The rsym and the found symbol are the same, so
the found symtree can be deleted.
PR fortran/34429
* decl.c (match_char_spec): Remove the constraint on deferred
matching of functions and free the length expression.
delete_symtree to gfc_delete_symtree.
(gfc_match_type_spec): Whitespace.
(gfc_match_function_decl): Defer characteristic association for
all types except BT_UNKNOWN.
* parse.c (decode_specification_statement): Only derived type
function matching is delayed to the end of specification.
