In the emacs manual (Info-index "obsolete command")
only finds

       When ‘M-x’ completes on commands, it ignores the commands that are
    declared “obsolete”; for these, you will have to type their full name.
    Obsolete commands are those for which newer, better alternatives exist,
    and which are slated for removal in some future Emacs release.

However one's .emacs file might be chock full of items such as

    x-select-enable-clipboard is a variable defined in ‘select.el’.
    Its value is nil

      This variable is an alias for ‘select-enable-clipboard’.
      This variable is obsolete since 25.1;
      use ‘select-enable-clipboard’ instead.

Therefore the manual should mention how to systematically weed out all
obsolete items that one has set in one's .emacs file.

Or there just answer the question 'Have I set any items that are obsolete?'.

Compile your .emacs, and the byte-compiler will flag obsolete
variables.

Sounds good. Maybe mention it in the Emacs manual as the way to find
obsolete variables in one's emacs file.

Alas, using
B runs the command dired-do-byte-compile (found in dired-mode-map),
gives:
Byte-Compile .emacs? (y or n) y
Compiling /home/jidanni/.emacs...
Byte compile error for /home/jidanni/.emacs:
t

And no file is written. Just one big blank *compilation* buffer.
Give it a try,

Bisect your .emacs to find where that happens, then take it from
there.

All I know is my .emacs runs fine with no errors.

It's just when I use
dired-do-byte-compile on it do I get a weird "t" error.
So it must be dired-do-byte-compile that has the problem.

Works for me, I got this (note that I didn't load your config though):

Works here - I can compile it (but get a bunch of warnings) - tried with
master and with Emacs 24.

Maybe, but we will never know unless you show which part causes that.

In any case, you asked for a way to check out your .emacs, and now you
have it.  Whether that problem with 't' is part of the issue or just
something to work around to get the byte compilation run to
completion, is a separate issue.

OK, dired-do-byte-compile works, it just takes a second run.
The very first run gives the "t" error, and only if you have loaded my
.emacs file. Otherwise it byte-compiles on the first run.

Anyway I hope the Emacs manual will add a section under
(info "(emacs) Init File")
mentioning how to keep your .emacs in top running shape, like changing
the oil in an automobile.

I think suggesting byte-compiling the .emacs file is a bit beyond the
scope of that user manual section, so I'm closing this bug report.
