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