Log Message:
Update to luit-1.0.3.  Notable changes:

  * Define _XOPEN_SOURCE to 500 on linux

  * strdup() is only exposed by glibc headers if _XOPEN_SOURCE is defined
    to a value >= 500.

  * Replace malloc/strcpy pairs with strdup

  * Man page typo fixes

  * Fix sparse warnings: non-ANSI function declaration (missing void)

  * Fix many sparse warnings of Using plain integer as NULL pointer

  * Change luit_CFLAGS to AM_CFLAGS to make automake-1.10 happier

  * Fix typo in luit.man

  * Match luit locale.alias location to libX11 default
    Luit expects to find the locale.alias file in ${libdir}/X11/locale.
    However, libX11 installs the locale files in ${datadir}/X11/locale,
    by default.
