Return NULL in basic_string_char dtor

Could you please give this patch a try?

The application is using only few functions from msvcp71, namely:
basic_string_char_ctor
basic_string_char_ctor_cstr
basic_string_char_assign_ch
basic_string_char_dtor

The only difference I can see is that native returns NULL in
basic_string_char_dtor (or uses EAX internally and lives it set to 0).

I couldn't find anything about value returned by destructors in abi
descriptions.
