* valprint.c (type_print_base): If the type being printed is a struct containing undefined types, print "<undefine type>" as the type instead of crashing. * values.c (value_headof): Get the vtable pointer taking TYPE_VPTR_BASETYPE into account. * symtab.c, symtab.h, dbxread.c: Fix various whitespace splotches.
