There's also a possibility to make this a tristate option instead of a
simple boolean one.  After all, it's quite possible that development
snapshots of GDB were available on several GNU/Linux distros for some
time, and so the argument of "new in GDB 7.0" is not necessarily
strong enough.

This is okay.

This seem to leave the option's name unaltered, unlike your
explanations and unlike the docs changes.  Or am I missing something?

This part is approved, assuming we agree to the code change and the
removal of the previous functionality,. and also subject to a couple
of comments:

> +@cindex print messages when shared object library symbols are loaded

This index entry is too long.  Suggest to shorten it like this:

  @cindex announce loading symbols from shared libraries

I would also add another one:

  @cindex shared libraries, announce loading symbols

> +The @code{set print solib-symbol-loading} command allows you to enable or

"This command" is shorter and doesn't lose any information, since the
name of the command is clearly visible at this spot.

Thanks.
