Hello,

I was getting the following error on emacs startup:

    Symbol’s function definition is void: speedbar-add-supported-extension

I tracked it down to the form in org-compat.el (line 873 in my copy):

    (eval-after-load "speedbar" ...)

This condition was being triggered because in my emacs init, I was
loading a file called "speedbar.el" which contained my speedbar
configuration.

I will understand if this is not considered a bug, because I can (and
have) rename my speedbar configuration script to a different filename.
However, I noticed that 'eval-after-load can take either a filename or a
feature symbol as its argument.  If the string "speedbar" were changed
to the symbol 'speedbar, the eval form would be triggered by speedbar's
'provide form, not only loading a file that happened to be called
"speedbar.el"

Thank you,

-John
