xemacs-21.4 / src / input-method-xfs.c

/* input-method-xfs.c provides just only locale initialize
   for non Motif people. (stoled from input-method-xlib.c)
   Why I made this code is to initialize X locale environment for
   the purpose of use XFontSet correctly in lwlib/xlwmenu.c.
   And this code donot provides input methods under Xlib while they
   prefer to use Canna, Wnn, skk or something like that.
   This code has been tested on FreeBSD 2.2.1 and Solaris2.5.
