I still don't understand why this test should differ between C and C++.

IIUC -- it declares the 'inty' typedef two different ways in two
different scopes, then tests that the expected output depends on the
scope:

Tom> +gdb_test "ptype inty" "type = int" "ptype in main"
Tom> +
Tom> +gdb_breakpoint "foo"
Tom> +gdb_continue_to_breakpoint "continue to breakpoint for foo"
Tom> +
Tom> +gdb_test "ptype inty" "type = unsigned int" "ptype in foo"


... if this is correct for C, why wouldn't it be correct for C++?
