Can I rely on "-shared" being available also in future versions of
clang/cc? Or is this a deprecated "gcc compatibility" option?

It is listed on as command line option:
But it does not come with any description on that website.

Building shared libraries is an important feature, so I'm a bit
surprised there is no documentation on on the "cc -shared" invocation
(other than GCC's documentation), or maybe I'm just looking at the
wrong places? Maybe you or someone else knows where else could I find
any documentation on this?
