@item -module
Creates a library that can be dlopenend (@pxref{Dlopened modules}).
-This option doesn't work for programs and must not be used
-together with @samp{-export-symbols}.
-It enables the option @samp{-export-dynamic} automatically.
+This option doesn't work for programs.
Module names don't need to be prefixed with 'lib'.
In order to prevent name clashes, however, 'libname' and 'name'
must not be used at the same time in your package.
By default, this macro turns on shared libraries if they are available,
and also enables static libraries if they don't conflict with the shared
libraries. You can modify these defaults by calling either the
-@code{AM_DISABLE_SHARED} or @code{AM_DISABLE_STATIC} macros:
+@code{AC_DISABLE_SHARED} or @code{AC_DISABLE_STATIC} macros:
@example
# Turn off shared libraries during beta-testing, since they

comma-separated @var{pkgs} list, and every other package with
@samp{--disable-shared}. The @samp{--enable-static=@var{pkgs}} flag
behaves similarly, but it uses @samp{--enable-static} and
-@samp{--disable-static}.
+@samp{--disable-static}. The same applies to the
+@samp{--enable-fast-install=@var{pkgs}} flag, which uses
+@samp{--enable-fast-install} and @samp{--disable-fast-install}.
The package name @samp{default} matches any packages which have not set
their name in the @code{PACKAGE} environment variable.

+Enable checking for dlopen support. This macro should be used if

+libtool will assume that the system does not support dlopening.
+The macro must be called *before* @code{AM_PROG_LIBTOOL}.
+@end defmac
+
+@defmac AC_DISABLE_FAST_INSTALL
+Change the default behaviour for @code{AM_PROG_LIBTOOL} to disable
+optimization for fast installation. The user may still override
+this default by specifying @samp{--enable-fast-install}.

+
+@defmac AC_DISABLE_SHARED

+@defmac AC_DISABLE_STATIC
+@defmacx AM_DISABLE_STATIC
Change the default behaviour for @code{AM_PROG_LIBTOOL} to disable
static libraries. The user may still override this default by
specifying @samp{--enable-static}.
@defvar always_export_symbols
Whether libtool should automatically generate a list of exported symbols
using @var{export_symbols_cmds} before linking an archive.
-Set to @samp{yes} or @samp{no}. Default is @samp{no}
+Set to @samp{yes} or @samp{no}. Default is @samp{no}.

+Linker flag (passed through the C compiler) used to generate thread-safe

@defvar version_type
The library version numbering type. One of @samp{libtool},
@samp{linux}, @samp{osf}, @samp{sunos}, or @samp{none}.
