I think I agree. I don't see a rationale in the DR other than the
confusing naming of something being "extern C" but not extern.

Given that gcc and msvc give these functions C language linkage, the
only advantage would be to clang only codebases that could use
overloaded static functions in a extern "C" context.

Richard, are you ok with assign_c_language_linkage.patch?
