Subject: [9front] Patch cc to create .$O files with DMTMP
Reply-To: 9front@9front.org
Precedence: bulk

Hello,

I often have times where I find I have left build artifacts around the system from forgetting
to run mk clean. I thought it might be nice for the compiler to create the files with DMTMP
to prevent them from getting added to fs dumps.


Thanks,
moody
