Hi,
I'm planing to make the following change in coreutils
so that autoconf can then use the exact same GNUmakefile.
The only difference for autoconf would be that it would
also require a new file, GNUmakefile.cfg, with this content:
----------------------
# Build with our own versions of these tools, when possible.
export PATH = $(shell echo "`pwd`/tests:$$PATH")
# Remove the autoreconf-provided INSTALL, so that we regenerate it.
_autoreconf = autoreconf -i -v && rm -f INSTALL
----------------------
Thus, for autoconf, making this change would induce no functional difference.
(for coreutils, it also fixes a tiny bug: it would fail to remove
$(srcdir)/autom4te.cache in VPATH builds)
I'll send an autoconf patch separately.
Here's the coreutils change:
===============================================================
Generalize GNUmakefile, ...
...so that it can be used unmodified by autoconf.
* GNUmakefile: Include optional file, GNUmakefile.cfg.
Autoconf will use this to override _autoreconf and to export PATH.
(_autoreconf): Define.
(_dummy): cd to $(srcdir) before removing autom4te.cache.
