1. Addition of maintainer-mode dependencies on config.status and
aclocal.m4 for autoconf toplevel Makefile.ins. These rules are taken
over from automake generated Makefile.ins, i.e. they are contained in
any automake generated toplevel Makefile.in. Having this patch in is at
least a great releaf for me when working on RTEMS configuration :)
2. Automated support for #1 in acpolish
3. Some minor "beautifications" on Makefile.ins resulting from running
acpolish.
FYI: This patch has been generated by running
tools/update/rtems-polish.sh -ac on the source tree and manually editing
the resulting patch afterwards to work around a problem with acpolish,
which still corrupts one Makefile.in - WARNING: Be careful with running
acpolish!
