+/* This file redirects the gettext functions (without prefix or suffix) to
+   those defined in the included GNU gettext library (with "__" suffix).
+   It is compiled into libintl when the included GNU gettext library is
+   configured --with-included-gettext.
+
+   This redirection works also in the case that the system C library or
+   the system libintl library contain gettext/textdomain/... functions.
+   If it didn't, we would need to add preprocessor level redirections to
+   libgnuintl.h of the following form:
+
+#    define gettext gettext__
+#    define dgettext dgettext__
+#    define dcgettext dcgettext__
+#    define ngettext ngettext__
+#    define dngettext dngettext__
+#    define dcngettext dcngettext__
+#    define textdomain textdomain__
+#    define bindtextdomain bindtextdomain__
+#    define bind_textdomain_codeset bind_textdomain_codeset__
+
+   How does this redirection work? There are two cases.
+   A. When libintl.a is linked into an executable, it works because
+      functions defined in the executable always override functions in
+      the shared libraries.
+   B. When libintl.so is used, it works because
+      1. those systems defining gettext/textdomain/... in the C library
+         (namely, Solaris 2.4 and newer, and GNU libc 2.0 and newer) are
+         ELF systems and define these symbols as weak, thus explicitly
+         letting other shared libraries override it.
+      2. those systems defining gettext/textdomain/... in a standalone
+         libintl.so library (namely, Solaris 2.3 and newer) have this
+         shared library in /usr/lib, and the linker will search /usr/lib
+         *after* the directory where the GNU gettext library is installed.
+
+   A third case, namely when libintl.a is linked into a shared library
+   whose name is not libintl.so, is not supported. In this case, on
+   Solaris, when -lintl precedes the linker option for the shared library
+   containing GNU gettext, the system's gettext would indeed override
+   the GNU gettext. Anyone doing this kind of stuff must be clever enough
+   to 1. compile libintl.a with -fPIC, 2. remove -lintl from his linker
+   command line.  */
