New in 2.4.2 2010-12-??: git version 2.4.1a, Libtool team:
+* New features:
+
+ - The --with-pic configure option now supports a list of comma-separated
+ package names. This can be used to build some static libraries with PIC
+ objects while building others with non-PIC objects.
+
* Bug fixes:
- The generic approximation of the command line length limit (when getconf is

+Add support for the @option{--enable-shared}, @option{--disable-shared},
+@option{--enable-static}, @option{--disable-static}, @option{--with-pic}, and
+@option{--without-pic} @code{configure} flags.@footnote{@code{LT_INIT} requires
+that you define the @file{Makefile} variable @code{top_builddir} in your
@file{Makefile.in}. Automake does this automatically, but Autoconf
users should set it to the relative path to the top of your build
directory (@file{../..}, for example).} @code{AC_PROG_LIBTOOL} and
The package name @samp{default} matches any packages that have not set
their name in the @code{PACKAGE} environment variable.
+The @option{--with-pic} and @option{--without-pic} configure flags can be used
+to specify whether or not @command{libtool} uses PIC objects. By default,
+@command{libtool} uses PIC objects for shared libraries and non-PIC objects for
+static libraries. The @option{--with-pic} option also accepts a comma-separated
+list of package names. Specifying @option{--with-pic=@var{pkgs}} is the same
+as configuring every package in @var{pkgs} with @option{--with-pic} and every
+other package with the default configuration. The package name @samp{default}
+is treated the same as for @option{--enable-shared} and
+@option{--enable-static}.
+
This macro also sets the shell variable @code{LIBTOOL_DEPS}, that you
can use to automatically update the libtool script if it becomes
out-of-date. In order to do that, add to your @file{configure.ac}:
# MODE is either `yes' or `no'. If omitted, it defaults to `both'.
