The references in in-file changelogs and the ChangeLog files have not
been modified. Only those references that refer to current practices
or locations.
The distclean target should only remove files that make creates. If
there are any that need taking care of, they should be added in on a
per file basis in the Makefile.am that creates it.
Upon re-reading the autoconf documentation, this seemed the right thing
to do. The AC_LANG_PROGRAM macro does not quote its arguments so any
occurence of [ and ] will get stripped out if not double quoted.
Current code snippets passed do not use them but it is better to use a
consistent quoting approach for such snippets. In other places in the
configure.ac file double quoting is used already.
This gets rid of a number of obsoleted macros and replaces RETSIGTYPE
with a void literal which can be assumed for C89 and later.
This changeset was prepared using autoupdate and modified to get rid of
whitespace and doubled [] changes. Changes to acinclude.m4 were added
by hand.
Several variables are considered "user variables" by the GNU Standards.
This means that the user can pass these to their ./configure and make
invocations as they see fit. These variables include CPPFLAGS, CFLAGS
and LDFLAGS.
This changeset pushes our use of these variables to the automake shadow
variables, AM_CPPFLAGS, AM_CFLAGS and AM_LDFLAGS, so that user variables
will no longer clobber flags required in order to build.
This addresses autoreconf output such as:
tools/Makefile.am:37: warning: source file '../backend/sane_strstatus.c' is in a subdirectory,
tools/Makefile.am:37: but option 'subdir-objects' is disabled
The option was introduced in automake version 1.9 and is slated for
unconditional activation with automake-2.0.
This name has been preferred since autoconf-2.52 and automake-1.5.
Both were released in the summer of 2001. Support for configure.in
is slated for removal in automake-2.0.
The configure.ac file itself requires autoconf-2.54 or later (and
does not care about the automake version).
