I have tried to compile today's djgpp cvs source tree using gcc 4.1.2
and binutils 2.17 on Windows 98SE and Win XP with DJ's patch applied.
Both compilations died with the following error message:

gcc ... -c symify.c
`-mcpu=' is deprecated. Use `-mtune=' or '-march=' instead.

Below there is a patch to fix minor issues that I noticed while compiling.
