Thanks, Gerald. This worked perfectly.
Also, thanks to everyone else for their suggestions. I appreciate the
feedback and read up on the suggested commands, but this ended up being the
easiest. :-)

Those are all good suggestions (although testing
exists("*Source_vimrc") seems a little complicated). One more
possibility is to put all function definitions, along with anything else
that never needs to be re-done, below a few lines like these:
" Skip the rest of the file if it has already been re-loaded.
if exists("s:deja_vu")
finish
endif
let s:deja_vu = 1
function Source_vimrc() " no need for the !, this should never be read twice.
...
BTW, another post on this thread pointed out that your vimrc file
knows its own name. As of vim 7.0, this name is also stored in the
$MYVIMRC environment variable.

Your .vimrc knows its own filename. Here is an exerpt from my .vimrc

Longer and more complicated, but now I can check to see if the file exists

This is on Windows XP. Thanks.
Encase your function like this:
if !exists("*Source_vimrc")
function Source_vimrc()
...
endfunction
endif
The reason you're getting the error is because you're sourcing the file
(vimrc) that produced/will override the function (Source_vimrc) you're
using at the moment.
A few words of advice to source your vimrc cleanly:
1. Define your functions in vimrc with "function!" so that when
sourced again, the functions will be overwritten.
2. Keep your autocmds in an augroup so that if it's sourced again, you
can delete the augroup and redefine it instead of adding more of
the same autocmds.
3. If you're using the FuncUndefined autocmd, delete those functions
that have been defined before.
For examples 2 & 3,
augroup vimrc
"delete augroup
autocmd!
...
silent! delfunction MyFuncInOtherFile
autocmd FuncUndefined MyFuncInOtherFile source
$HOME/.vim/autoload/MyFuncInOtherFile.vim
...
autocmd ...
...
augroup END
