I started a  discussion about this on egcs-bugs  in early October last
year  (look  for `egcs-970929:  Install   c++filt' in  the archive for
details about it); we didn't come to a final agreement ;-(

Anyway,  here is an updated version  of the patch I submitted relative
to the CVS tree as of 1998/02/13 16:33:18:

Sat Feb 14 11:50:51 1998  Manfred Hollstein  <manfred@s-direktnet.de>

	* Make-lang.in (DEMANGLER_INSTALL_NAME, DEMANGLER_CROSS_NAME): New macros.
	(c++.install-common): Install c++filt properly as native or as cross
	variant.
	(c++.uninstall): Add c++filt.
