Well, the C++ ABI refers to this as "vague linkage." It may be a bit too long or too ABI-specific, but maybe something like -f[no-]use-vague-linkage-for-functions or -f[no-]functions-vague-linkage? And perhaps note in the doc that using this option may technically break the C++ ODR, so it should be used only when you know what you're doing. -cary
