See comments to bug #274.
Now it should show a warning...

If this only works with MSVC isn't it better do surround it by #ifdef _MSC_VER ?

[Leon Bottou]

It works with compilers that implement the MSVC pragmas (the intel compiler maybe).

Anyway I just wanted to make sure it would either fail to compile or at least give a warning.
