Compilation problem in xemacs

[Uday Reddy]

The 8.1 devo version fails to compile in XEmacs. configure produces the output (the relevant section)

checking otherdirs... Reading directory /home/staff/udr/xemacs/vm/8.1/lisp/...
Reading directory /home/staff/udr/xemacs/vm/8.1/lisp/...done

xemacs exiting
.Cannot open load file: conftest.el

The error message "Cannot open load file: conftest.el" ends up being the value of OTHERDIRS in lisp/Makefile, breaking the compilation process.

This problem is not present in 8.0.x.

Rob and Ulrich, I need your help with this xemacs compilation problem. Can you double check that the following fix makes sense? I don't quite understand the configure files and I am only guessing. -- Uday

The patch looks safe to me. XEmacs doesn't have an -L option, and the
additional dir in the load-path is only needed to find vm-build.el.
