25 gettext() and dgettext(). It is specified in POSIX, but not in ANSI C.

27 On Solaris, <locale.h> defines __LOCALE_H (or _LOCALE_H in Solaris 2.5)
28 then includes <libintl.h> (i.e. this file!) and then only defines
29 LC_MESSAGES. To avoid a redefinition warning, don't define LC_MESSAGES

67 library (namely, Solaris 2.4 and newer, and GNU libc 2.0 and newer).
68 If we used the unprefixed names, there would be cases where the
69 definition in the C library would override the one in the libintl.so
70 shared library. Recall that on ELF systems, the symbols are looked
71 up in the following order:
73 2. in the shared libraries specified on the link command line, in order,
74 3. in the dependencies of the shared libraries specified on the link
76 4. in the dlopen()ed shared libraries, in the order in which they were
78 The definition in the C library would override the one in libintl.so if
80 * -lc is given on the link command line and -lintl isn't, or
81 * -lc is given on the link command line before -lintl, or
82 * libintl.so is a dependency of a dlopen()ed shared library but not
83 linked to the executable at link time.
84 Since Solaris gettext() behaves differently than GNU gettext(), this
85 would be unacceptable.
87 The redirection happens by default through macros in C, so that &gettext
88 is independent of the compilation unit, but through inline functions in
89 C++, in order not to interfere with the name mangling of class fields or
90 class methods called 'gettext'. */
