+Subject: [PATCH] bootstrap: Use gnulib-tool from PATH if available.
+
+Some distributions such as GNU Guix include in their package for
+gnulib a 'gnulib-tool' command under their $bindir
+prefix (e.g. '/bin') for users to use, along the unmodified full
+sources.  The idea is that any wrapping or distribution modifications
+for the *execution* of the script at run time is done on these
+commands, while the rest of the source should be in their
+pristine (unmodified) version.  Adjust the 'gnulib-tool' discovery
+mechanism to support such installation layout.
+
+* build-aux/bootstrap (autogen) <gnulib_tool>: Prefer to use from
+PATH, else from $GNULIB_SRCDIR/../../bin/gnulib-tool, else from
+$GNULIB_SRCDIR/gnulib-tool.
+* gnulib-tool.sh (func_gnulib_dir): Honor GNULIB_SRCDIR to locate
+gnulib's main directory.
