I suppose this is really a question for the autoconf folks, as it
affects more in our configure scripts than just libtool.

Subject: libtool AC_ARG_WITH and autoconf 2.59

I know that autoconf 2.13 generated the help text for AC_ARG_ENABLE and
AC_ARG_WITH in the order in which they appeared in the configure.in
file, but now I'm working with autoconf 2.59 and it appears to collect
all AC_ARG_ENABLE text into one group, followed by all the AC_ARG_WITH
options in a separate group. So in 2.13, where my configure --help shows
####
Library Generation & Linking Options
--enable-static[=PKGS] build static libraries [default=yes]
--enable-shared[=PKGS] build shared libraries [default=yes]
--enable-fast-install[=PKGS] optimize for fast installation
[default=yes]
--with-gnu-ld assume the C compiler uses GNU ld [default=no]
--disable-libtool-lock avoid locking (might break parallel builds)
--with-pic try to use only PIC/non-PIC objects
[default=use both]

With autoconf 2.59 I get
####
Library Generation & Linking Options
--enable-static[=PKGS]
build static libraries [default=yes]
--enable-shared[=PKGS]
build shared libraries [default=yes]
--enable-fast-install[=PKGS]
optimize for fast installation [default=yes]
--disable-dependency-tracking speeds up one-time build
--enable-dependency-tracking do not reject slow dependency extractors
--disable-libtool-lock avoid locking (might break parallel builds)
Optional Packages:
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
--with-subdir=DIR change default subdirectory used for installs
--with-cyrus-sasl with Cyrus SASL support auto
--with-fetch with fetch(3) URL support auto
--with-threads with threads auto
--with-tls with TLS/SSL support auto
--with-yielding-select with implicitly yielding select auto
--with-multiple-precision
multiple precision support for statistics
auto|bignum|gmp auto
--with-gnu-ld assume the C compiler uses GNU ld [default=no]
--with-pic try to use only PIC/non-PIC objects [default=use
both]
--with-tags[=TAGS]
include additional configurations [automatic]

I find this rather disturbing because it totally breaks up the logical
grouping of options that we try to create in our scripts. I'm still
reading the autoconf 2.59 document to see if there's a macro to control
this behavior, but in the meantime one fix would be to change libtool's
AC_ARG_WITH invocations into AC_ARG_ENABLE instead. Since the autoconf
behavior appears to reserve AC_ARG_WITH solely for specifying external
packages, instead of for specifying options, this would seem to be the
correct fix. Any thoughts?
