Inlining -- what happened to the inline keyword

[Robert Lupton]

In the distant past (1984?) I thought, from reading this newsgroup,
that the keyword `inline' was being proposed for ANSI C, to declare
that a function should be expanded inline. When I got back on the net
in 1987 or so it had dissapeared, and I've been wondering ever since 
why it was killed. Ditto with comments to end of line // this is a comment

Both have prior art (in C++), so that can't have been the reason. Can
anyone (I hope not many more than one) enlighten me?
