This is correct (both about linking and about "static" being deprecated in C++). Note that Stroustrup's recommendation is to use an anonymous namespace around source-file-local variables and functions rather than declaring them static (due to its deprecation). From my recollection this is not precisely equivalent in meaning but it is nearly so. I have seen and used both in WebKit (although "static" is more common) and I believe the Google style guide also allows both. PK
