Ok, good. Thus far only argument was "historically they have existed",
which does not sound good enough worry about them. If somebody is
actually testing and caring abouth such compilers, they need to be
taken more seriously.

Note - my advanced proposal (instead duplicate macros, let 'static inline'
functions fall back to being plain 'static') would still support
non-inline compilers, but with potentially small performance hit.
So the plain-C89 compilers would be downgraded to "second-class"
targets, not worth getting max performance out of them.
Is this OK?
