It *says*: --with-xim=xlib Compile with support for X input methods, --with-xim=motif (*) Used in conjunction with Mule support. Use either raw Xlib to provide XIM support, or the Motif XmIm* routines (when available). NOTE: On some systems bugs in X11's XIM support will cause XEmacs to crash, so by default, no XIM support is compiled in, unless running on Solaris and the XmIm* routines are detected. In fact, the test is "unless using Motif and the XmIm* are detected", as it quite cheerfully auto-detected xim=motif on a RedHat box using OpenMotif. /Valdis
