1169. Missing feature macro for strict pointer safety

[Voted into the WP at the November, 2010 meeting.]

The recommendations of document N2693 included a feature macro to enable a program to determine whether the implementation enforces strict pointer safety or not, but this macro is not specified in 15.11 [cpp.predefined].

Proposed resolution (August, 2010):

Add the following to the end of 15.11 [cpp.predefined] paragraph 2:

__STDCPP_STRICT_POINTER_SAFETY__
Defined, and has the value integer constant 1, if and only if the implementation has strict pointer safety (_N4885_6.7.5.5.4 [basic.stc.dynamic.safety]).
