>Description:
The attached code shows the scenario in which use of the ?: operator with const static member variables creates references to variables that ultimately the linker (ld) is not capable of finding.

The attached code demonstrates, and documents, variations that clearly isolate the ?: operator being used with const static members (note that both results have to be const static for the effect to appear).
