* 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.
