--- Comment #14 from Maciej S. Szmigiero <mail at maciej dot szmigiero.name> --- > This is not so useful in practice because most compilers don't make extern > "C" and extern "C++" differentiate function types (implying calling > conventions etc.). The standard allows different calling conventions for "C" and "C++" language linkage and that's what matters when writing standard-compliant code - one shouldn't write to a particular implementation (or implementations). > > All functions and variables whose names have external linkage and all > > function types have a language linkage. > > which implies that a function with internal linkage doesn't have a language > > linkage, and thus [dcl.link]/7 doesn't apply to it. Nothing in the above quote says that *only* these specified have a language linkage, just that these explicitly enumerated sure do.
