29 /* This file redirects the gettext functions (without prefix or suffix) to
30 those defined in the included GNU gettext library (with "__" suffix).
31 It is compiled into libintl when the included GNU gettext library is
32 configured --with-included-gettext.
33
34 This redirection works also in the case that the system C library or
35 the system libintl library contain gettext/textdomain/... functions.
36 If it didn't, we would need to add preprocessor level redirections to
37 libgnuintl.h of the following form:
38
39 # define gettext gettext__
40 # define dgettext dgettext__
41 # define dcgettext dcgettext__
42 # define ngettext ngettext__
43 # define dngettext dngettext__
44 # define dcngettext dcngettext__
45 # define textdomain textdomain__
46 # define bindtextdomain bindtextdomain__
47 # define bind_textdomain_codeset bind_textdomain_codeset__
48
49 How does this redirection work? There are two cases.
50 A. When libintl.a is linked into an executable, it works because
51 functions defined in the executable always override functions in
52 the shared libraries.
53 B. When libintl.so is used, it works because
54 1. those systems defining gettext/textdomain/... in the C library
55 (namely, Solaris 2.4 and newer, and GNU libc 2.0 and newer) are
56 ELF systems and define these symbols as weak, thus explicitly
57 letting other shared libraries override it.
58 2. those systems defining gettext/textdomain/... in a standalone
59 libintl.so library (namely, Solaris 2.3 and newer) have this
60 shared library in /usr/lib, and the linker will search /usr/lib
61 *after* the directory where the GNU gettext library is installed.
62
63 A third case, namely when libintl.a is linked into a shared library
64 whose name is not libintl.so, is not supported. In this case, on
65 Solaris, when -lintl precedes the linker option for the shared library
66 containing GNU gettext, the system's gettext would indeed override
67 the GNU gettext. Anyone doing this kind of stuff must be clever enough
68 to 1. compile libintl.a with -fPIC, 2. remove -lintl from his linker
69 command line. */
