Ada gurus,
I've seen recent posts that describe compilation of the GNAT runtime system as
a shared library, as well as calling external C functions. (Of course, the
latter capability is part of the standard.)
What I haven't figured out, though, if it is possible to export an Ada
function/procedure as a C function in a shared library.
The commercial compiler ObjectAda seems to be able to do this. Can I do the
same with GNAT?

Yes, of course this is possible, why would you think it might not be. The
question is equivalent to whether it is possible to write a C function
in a shared library! pragma Export has exactly the effect of making an
Ada routine equivalent to a C one in terms of naming, parameter
passing mechanism etc.
