From what I understand the current implementation does not conform to the posix implementation. If you compile with _APPLE_C_SOURCE, _POSIX_C_SOURCE or _XOPEN_SOURCE, the implementation should behave as you want. This email sent to site_archiver(a)lists.apple.com

From what I understand the current implementation does not conform to the posix implementation.

Variant is used in MFC Class. I want to use Variant on MAC OSX with gcc 4.0 and xcode 2.2. Is there any replacement for Variant is on Mac or we can use them same as in MFC Classes. That's just an exercise in unions, for many purposes. Unions have the benefit of being standard C, though. smime.p7s

Okay, you're hosed. This is not a feature of the language. Indeed, it's a feature of some standard Windows library. It's possible to implement support for it in any language (also on non- Windows platforms), but that's quite a bit of work. I don't know of a pure C implementation.
