Hi Roger,

I would put the #pragma inside an #if defined(_MSC_VER)
You can check for the _MSC_VER if you just want to use those pragma for 
a specific version of VC.

Here is an example:

#if defined(_MSC_VER)
    #pragma warning( disable : 4290 ) // we don't care about exception 
specification ignored
#endif
