I’m looking for a portable version of __if_exists (VS.NET keyword) and unfortunately google turned up nothing good.

I use boost fairly regular and checked boost::type_traits but found nothing that seemed to similar.

Has anyone heard of something that can accomplish this?

It might help if you described what it does.

full explanation: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclang/html... short explanation: __if_exists allows you to conditionally include code depending on whether the specified symbol exists. __if_exist ( variable ) { statements } where: variable The symbol whose existence you want to test for. statements One or more statements to execute if variable exists.
