[PATCH 1/2] maint: make position of gnulib checkout configurable


From: Stefano Lattarini
Subject: [PATCH 1/2] maint: make position of gnulib checkout configurable
Date: Sat, 21 Jan 2012 10:52:25 +0100

Some gnulib-related tools (most prominently, the gnulib-provided
'bootstrap' script) allow the user to define the position of his
gnulib's repository checkout through the use of the 'GNULIB_SRCDIR'
environment variable.  We should do the same, for consistency and
to easily support slightly unusual layouts in developers' source
trees.

* cfg.mk (gnulib_dir): Define to "$GNULIB_SRCDIR" if that's set,
and to default value of "'$(abs_srcdir)'/../gnulib" otherwise.
Update comments.
