[Andy Wingo <wingo@pobox.com>]

Hi,

On the "wingo" branch in the main repository, you will find the
following patches:

    The following changes since commit 0fe95f9c4ce063781e79a15bc123c57c33ef9755:
      Ludovic Courtès (1):
            Improve wording in `libguile/Makefile.am' regarding stack calibration.

    are available in the git repository at:

      git.sv.gnu.org:/srv/git/guile.git wingo

    Andy Wingo (7):
          allow building against uninstalled guile; move some things to meta/
          add getrlimit and setrlimit wrappers
          getrlimit-based stack limits
          rely on getrlimit to DTRT, don't make stack calibration file
          fix check for guile-tools running uninstalled
          fix "linking" of guile-config
          fix distcheck hopefully, by cleaning the vm-i-*.i files

The patches fix distcheck again, but the interesting one is
