    # Without a call to bindtextdomain(), gettext() will search in
    # libintl's default LOCALEDIR, which is set at compile time. The
    # most common case is:
    # $datadir/locale = $prefix/share/locale = /usr/share/locale

    # However we could run on a PHP+gettext compiled with, say,
    # prefix=/usr/local; that's why the gettext documentation
    # recommends to always use bindtextdomain() at application
    # initialization, using the app's LOCALEDIR (and not
    # libintl's). This also avoid messing with /usr when installing
    # in /usr/local.

    # Check <gettext-source>/gettext-tools/examples/hello-php/ for an
    # autoconf example. One solution is autoconfiscating the PHP app
    # to set @localedir@; another is to use the configuration file,
    # and default to gettext's default path (ie. don't call
    # bindtextdomain is $sys_localedir is empty).

    # We still need this variable for the .po Makefile. For that part
    # (PO), let's use autoconf.
