Subject: Merge bootstrap changes from coreutils.
X-Git-Tag: v2.3b~280
X-Git-Url: https://git.saurik.com/bison.git/commitdiff_plain/e3ddc1e355923e9565e1ef66230389c7aa2954a3

Merge bootstrap changes from coreutils.

2006-09-28  Jim Meyering  <jim@meyering.net>

Automatically generated dependencies are important even
when all of the sources in a directory come from gnulib.
* bootstrap (gnulib_tool): Remove the "no-dependencies" automake
option that gnulib-tool adds to what becomes our lib/gnulib.mk.

2006-09-23  Jim Meyering  <jim@meyering.net>

* bootstrap (gnulib_tool_options): Add "--local-dir gl".

2006-09-20  Paul Eggert  <eggert@cs.ucla.edu>

* bootstrap: Add support for --force.
(usage): New function.  Describe usage less tersely.
(CVS_only_file): New var.
