Re: behavior of overwriting running executables?

I wanted behavior to unlink the file when linking since I have problems:
1) when I'm setuiding a program I'm working on (I normally have to
rm in the makefile
2) when I'm leaving the binary running (normally a mistake).
I want the link to proceed without a problem (linux reports
"text file busy"

This seems correct and I don't see harm...

Comments? You want to put it in?

It in HJ Lu's 2.6.0.13 linux binutils distribution.
