[gimp-0.99.11, gtk+970916] i18n-locale on linux

["Yoichi `ASR' Izumi" <izumi vit or jp>]

hi developers,

on linux, libc does not support i18n-locale. so, let's use X11's
setlocale() instead of libc's.
(in original i18n-patch, X11's has been used.)


i.e:

in gtk+/gdk/gdk.c
  #include <locale.h> -> #include <X11/Xlocale.h>

and define X_LOCALE in Makefile.

that's all.


thanks,
