Hi Jim,

Following this recent change of yours:

> * bootstrap.conf (gnulib_modules): Reflect renamings

I see the following after running ./bootstrap:

    - invoke gl_INIT in ./configure.ac.
    ./bootstrap.conf: line 136: build-aux/prefix-gnulib-mk: No such file or directory
    running: AUTOPOINT=true LIBTOOLIZE=true autoreconf --verbose --install --force -I m4  --no-recursive

Since gnulib-tool --automake-subdir handles the prefix-gnulib-mk for us
now, the work can be removed from bootstrap.conf. Patch attached.

Collin

P.S. I'll send in the copyright forms for cppi since I think my previous
patch reached the ~10 line limit anyways.
