[omniORB] Visual Studio 2008 level 4 compiler warnings

[William Bauder]

Any reason for the do..while?  The braces alone should suffice.

Thanks for the patch. It makes sense for trunk, and I'll put something along those lines in. Perhaps you can send it again as an attachment, because it has become a bit mangled in the email body?

I'm afraid it can't be in the 4.1.7 release. The cdrStream layout is quite different in trunk (which will be the 4.2.x release) to what's in 4.1.x. The 4.2.x version can't be back-ported to 4.1.x because it's binary incompatible. 4.1.x uses the CdrMarshal and CdrUnmarshal macros rather more.

Anyway, I think the compiler warning is incredibly unwise. A do .. while
(0) loop is the standard way of defining a macro that's safe to use like a function. Surely the warning triggers on any robust macro code?

Cheers,

Duncan.
