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.

A copy of the license is included in the ``GNU Free @c Documentation License'' file as part of this distribution. The @code{c-strtod} module contains a string to number (@samp{double}) conversion function operating on single-byte character strings, that operates as if the locale encoding was ASCII. (The "C" locale on many systems has the locale encoding "ASCII".) The function is: @smallexample extern double c_strtod (const char *string, char **endp); @end smallexample In particular, only a period @samp{.} is accepted as decimal point, even when the current locale's notion of decimal point is a comma @samp{,}, and no characters outside the basic character set are accepted. On platforms without @code{strtod_l}, this function is not safe for use in multi-threaded applications since it calls @code{setlocale}.
