I'm not on the steering committee.  But, I think this would be a
useful feature in general -- if I understand `naked' correctly to mean
a function without a prologue or epilogue.  For example, thunks in C++
could then be represented as ordinary functions, not with assembly
code.

However, I'm not convinced that such things should never be inlined,
in the abstract.  What I'm convinced of is that GCC can't handle
inlining them at the moment.  So, the documentation for `naked'
functions should explicitly say that they might be inlined in a future
release, etc., etc.
