A patch for toplevel Makefile.in

["H . J . Lu" <hjl at valinux dot com>]

Hi,

I checked in the patch enclosed here into binutils. The detailed
discussions can be found at

http://sourceware.cygnus.com/ml/binutils/2000-03/msg00116.html
http://sourceware.cygnus.com/ml/binutils/2000-03/msg00133.html

and their followups. I suggest gcc should also consider this patch.

Thanks.
