Cool!  I think we can drop the cygwin ML list from CC then.

Fine with me.

A big problem for many people keeping them from provide patches to the
configury is that newlib's build system still requires the automake
--cygnus option, which isn't supported by automake for quite some time.

And one of the effects of --cygnus is: to enables option "no-dependencies",
thus turning off dependency tracking.  Hrmpf.

Oh!  I really didn't know that.

I didn't either, until I looked it up and found

	info Automake-1.11 Cygnus

So here's the slightly amended recipe, as discovered so far:

1) Get rid of for'cygnus' options. In all 134 replace

by 	AUTOMAKE_OPTIONS = foreign no-installinfo no-dist
and delete cygnus from one or two AM_INIT([]) calls, too

2) autoupdate in newlib, using autoconf-2.69 and automake-1.15

2.1) fix some breakage inserted by autoupdate (LT_INIT wants to be updated manually, some spurious __au_m4_changequote()),
2.2) repeat from 2) until no more errors

3) autoreconf in newlib, using autoconf-2.69 and automake-1.15

3.1) add AM_PROG_AS to acinclude.m4, or autoreconf refuses to work
3.2) repeat from 3) until no more errors

If you're willing to provide a patch, the patch does not have to contain
the generated files.  I would create them locally and push the result.

Well, OK, so here goes. The core of the modification is best expressed as a pseudo shell script (don't run this without double-checking it!)

cd newlib
find . -type f -name '' | \
xargs sed -i -e '/AUTOMAKE_OPTIONS.*=/s/cygnus/foreign no-installinfo no-dist/'
cd ..

and then apply the attached patch "newlib-de-cygnussify-remaining-patch.diff" for the finer details, fix auto-tools to latest versions, then autoupdate, autoreconf.

main::scan_file() called too early to check prototype at
/usr/bin/aclocal-1.11 line 644.

Yeah, I was already wondering about this.  Patches *extremely* gratefully

All I can see off-hand is that scan_file() calls itself recursively in that line 644, which would tend to explain that message. aclocal-1.12 gets rid of that by adding prototype declarations (lines 156 ff.). Back-porting most of those prototypes into 1.11.6 appears to get rid of this warning without too much pain.

A real Perl programmer should look over this, though.

That did not work for me. config/override.m4 insisted rather strictly that
only 2.64 is allowed to be used.  I shredded lines 30ff. from that file to
get past that one.

Same here.  Neither Jeff nor I are autotools experts, so we would be
mightly happy if we could get patches to pull the repo to a newer
autotools state.

Well, FWIW, the attached lift-autconf-version-restriction.diff bluntly removes that restriction. I won't guarante the absence of any adverse effect, thoughe ;-)

And just in case: yes, all these patches are free for unrestricted used by the public.
