That is a bug.

This is not a bug, realize that without the src release installed if we
did this you could not use the system for compiling.  Bill did that
with 386BSD 0.1 and folks screamed about having to get part of the
src tree to be able to compile.  It was _fixed_ in FreeBSD 1.0 and
all later releases.

We need to ``enhance'' the installation of the src tree, that is where
the bug lies.  When a src tree is installed then and only then should
this symlink be made.  Infact right after a src install a
``cd /usr/src; make SHARED=symlinks includes'' would be the proper
thing to do.

I have in all of my /etc/make.conf files done just the opposite for
my own reasons (SHARED=copies) as I don't like my mucking around
in the /usr/src area to be any way visible to the running system,
if I want a change visible I run a make install.

The other real fix to this is to get on with the -no-std-includes that
has fallen into the deep deep cracks of time.

Your proposed symlink is just not really the right _fix_ for this bug :-(.
