History
Gary V. Vaughan 5dfb0ce7e2 Factor out the individual loaders, in preparation for preloading 
them as libtool modules.  Currently loader-preopen.c is linked
unconditionally and other appropriate loaders discovered by
AC_LTDL_DLLIB are built and linked in:

* libltdl/Makefile.am (libltdl_la_SOURCES): Add loader-preopen
module.
* m4/ltdl.m4 (AC_LTDL_DLLIB): Use AC_LIBOBJ to add appropriate
loaders to libltdl.
* libltdl/lt_system.h (LT_SCOPE): Moved to here.
* libltdl/ltdl.h (lt_dlloader, lt_user_data, lt_module)
(lt_module_open, lt_module_close, lt_find_sym, lt_dlloader_exit)
(struct lt_user_dlloader, lt_dlloader_next, lt_dlloader_find)
(lt_dlloader_name, lt_dlloader_data, lt_dlloader_add)
(lt_dlloader_remove): Moved declarations...
* libltdl/lt_loader.h: ...to here.
* libltdl/ltdl.c: Include lt_loader.h.  Move loader implementation
code from here...
* libltdl/loader-dld_link.c, libltdl/loader-dlopen.c,
libltdl/loader-dyld.c, libltdl/loader-load_add_on.c,
libltdl/loader-loadlibrary.c, libltdl/loader-preopen.c,
libltdl/loader-shl_load.c: ...to here.
* tests/cdemo/Makefile.am, tests/demo/Makefile.am,
tests/depdemo/Makefile.am, tests/f77demo/Makefile.am,
tests/mdemo/Makefile.am, tests/mdemo2/Makefile.am,
tests/pdemo/Makefile.am, tests/tagdemo/Makefile.am (AM_CPPFLAGS):
Add -I$(top_srcdir)/../.. so that libltdl include files can be
written as #include <libltdl/lt_dlloader.h> and found correctly.

README 

This is mdemo, an example package that uses GNU libtool with an
Automake-generated environment to build two simple modules and 
a program.

It demonstrates how to build both dynamic and static libraries
that can be dlopened. mdemo uses libtool's portable dlopen
wrapper called "libltdl". 
All exported symbols are prefixed with "libname_LTX_" to avoid
symbols conflicts, especially when linking statically.
libltdl will automatically cut the prefix off to get the real name.

Note that on Windows, for the purposes of illustrating ltdl, the
libraries *are* built as dll's, but do not have the __declspec
machinery to make them suitable for loading at link time.  This is
only for clarity inside this example, look at the example in ../demo
to see how the __declspec macros should be set up.
