        thnak you for explaining me the issue.
When I look back to my post, I guess it wasn't very bright.
I'll try to do better today ;-)

Sure, I had this in mind, but I didn't want to make the mail even longer.

I think this is the best possible solution as far as scripts are concerned.

I had a private e-mail discussion with Martin Kraemer (the orig. poster).
I have also mentioned this variant and he replied:

So we have three variants:
1) symlinks
2) scripts (with hardwired paths)
3) copies of binaries

I still don't understand why are the guidelines aginst the old symlinks variant
(BTW, the code is still there in grep.c from 2.5.1 ;-)
Could someone please explain me where this idea comes from?
Does it represent a security risk?

Could all of these variants be just install options?
(Probably --enable-* options to the configure script?)
If I prepare a patch, does it have a chance to be accepted?

Thanks in advance for (even more) explanation,
