	Hi and happy new year.

	I have uploaded my patch against 15.2.0 on
ftp://newton.systella.fr/gcc/patch.zip

	Warning, ftp server runs on an OpenVMS server. Don't forget binary
transfers.

	Patch applied, I configure gcc with :
hilbert:[~/cvs/gcc/build-15.2.0] > ../gcc-15.2.0/configure
--program-prefix=m6809- --target=m6809 --prefix=/home/bertrand/cvs/gcc/

	I have modified some files but I got following error :
