Yes. I was 99.9% sure, but since you asked I wrote this script and it
makes me 100% sure.
#! /usr/bin/perl -w
$_ = "\@defcodeindex fu";
/^\@def(code)?index (\w+)/;
print "\$1 = $1, \$2 = $2\n";
$_ = "\@defindex fu";
/^\@def(code)?index (\w+)/;
print "\$1 = $1, \$2 = $2\n";
Output:
$1 = code, $2 = fu
Use of uninitialized value in concatenation (.) at ./test line 7.
$1 = , $2 = fu

Tom, I'm worried about you. Don't you know that Automake has its
documentation in the top-level directory?
Try recent Autoconf or Libtool:
$ automake
$ ./configure --quiet
...
$ make dvi
make: Nothing to be done for `dvi'.
