relocatable-prog: Use wrapper-free installation on Mac OS X, take 2. This approach supports relocatable installation of shared libraries which depend on other shared libraries from the same package. * m4/relocatable.m4 (gl_RELOCATABLE_BODY): Determine use_macos_tools. If use_macos_tools is true, use reloc-ldflags and set LIBTOOL to be a wrapper around the original LIBTOOL. * build-aux/reloc-ldflags: Add support for Mac OS X, which uses the token '@loader_path' instead of '$ORIGIN'. * build-aux/libtool-reloc: New file. * modules/relocatable-prog (Files): Add it. * doc/relocatable-maint.texi (Supporting Relocation): Update to match the recent changes. Document the need to set the *_LDFLAGS of libraries. RELOCATABLE_LIBRARY_PATH and RELOCATABLE_CONFIG_H_DIR should be set in Makefile.am, not in configure.ac.

If you want it to be possible to compile your program for a native Windows
platform and you use Libtool, you need to use the @code{win32-dll} option of
@code{LT_INIT}. In other words, put:

@example
LT_INIT([win32-dll])
@end example

in your @file{configure.ac}.  This sets the correct names for the
@code{OBJDUMP}, @code{DLLTOOL}, and @code{AS} tools for the build.

If you are building a library, you will also need to pass
@code{-no-undefined} to make sure Libtool produces a DLL for your
library.  From a @file{Makefile.am}:

@example
libgsasl_la_LDFLAGS += -no-undefined
@end example
