Subject [jira] Commented: (STDCXX-637) [_MSC_VER] 21.cwchar test fails
Date Sat, 03 Nov 2007 00:06:51 GMT

Martin Sebor commented on STDCXX-637:
-------------------------------------

I'm not what the best approach to the first set of assertions (the ones for the shadow macros)
is. The macros are usually provided for efficiency and rarely cause problems so I don't feel
comfortable #undefining them just to satisfy strict conformance requirements and penalizing
programs that don't run into any name clashes because of them. One option for dealing with
them might be to undefine the macros in strict mode and leaving them alone otherwise (and
doing the same in the test -- i.e., adjust the strictness of the test based on the strictness
of the library).

As for the rest of the assertions (i.e., those for the undefined symbols), unless there actually
is something we can do about them (e.g., provide our own definitions), I think replacing the
assertions with warnings might be the way to go.
