+ * ltmain.sh.in (link): Add -dlopen and -dlpreopen support for
+ libtool objects. This means that dlopened modules no longer need
+ to be shared libraries.
+
+ * ltconfig.in (pic_flag): GCC on Irix 6 always builds PIC.
+ Reported by Ian Lance Taylor.
+
+ * libtool.m4 (LD): Always add `-n32' to the linker if we are using
+ GCC on Irix 6. Reported by Ian Lance Taylor.

+
+ * libtool.m4 (AM_PROG_LIBTOOL): Explicitly check enable_shared and
+ enable_static rather than just enableval. This allows
+ configure.in scripts to set their own defaults. Suggested by
+ Tommy Reilly.

* ltmain.sh.in: Add NLS environment variable handling copied from
ltconfig.in. Reported by Akim Demaille.
+ (link): If allow_undefined_flag is not supported, then turn on old
+ libraries. Reported by Akim Demaille.
* demo/dlmain.c (main): Use dld_preloaded_symbol_count to display
a message about the sortedness of the symbol table.
flags.
* New tests for a BSD-compatible `nm' program, required for dlopened
modules.
+* Allow configure.in to change the defaults for AM_PROG_LIBTOOL's
+ `--enable-{shared,static}' by setting `enable_{shared,static}=no'.

New in 1.0:
* Bug fixes.
+* Kenneth Albanowski suggests an `execute' mode, where the paths from
+libtool libraries are extracted and put into shlibpath_var, then a
+command is executed with the wrapped binary as argument.
+
+ KA> And 'libtool --mode=execute java test Java/libJavaPisock.la
+ KA> libsock/libpisock.la' turns into:
+
+ KA> LD_LIBRARY_PATH="libsock/.libs:Java/.libs" java test
+
+I think this is a good idea, but the nonobvious behaviour with libtool
+library arguments should be enabled by a flag, such as -dlopen LIB.
+Maybe -dlpreopen LIB should put these libraries in LD_PRELOAD.
+
+Use *db | *dbx as triggers for this mode.
+
+* Implement full multi-language support. Currently, this is only for
+C++, but there are beginnings of this in the manual (Other Languages).
+This includes writing libtool not to be so dependent on the compiler
+used to configure it.
+
+We especially need this for C++ linking, for which libtool currently
+does not handle static constructors properly, even on operating
+systems that support them. ``Don't use static constructors'' is no
+longer a satisfactory answer.
+
* Another form of convenience library, suggested by Alexandre Oliva,
is to have undocumented utility libraries, where only the shared
version is installed.
* A better check to detect broken collect2 on AIX, once the bug is
fixed in GCC.

* Need to finalize the documentation, and give a specification of
`.la' files so that people can depend on their format. This also
needs to be done so that DLD uses a public interface to libtool
## configuration script generated by Autoconf, you may include it under
## the same distribution terms that you use for the rest of that program.
