Hi,

I have been having a bit of a go at understanding boot-9.scm. While 
investigating it, i found out an interesting bit where SCM code is 
compiled to new .GO code when performing fresh-compilation. I found 
similar code in the C sources in load.c.

Now I wanted to add an option to disable the display of the compilation 
messages so went ahead with creating such an option. However, before I 
continue, I want a discussion about two things:

- Shouldn't it be that either the C code or the SCM is responsible for 
displaying the messages? If so, I would assume the C code should be 
changed to have formal procedures to handle these things.

- Also, is this option in general wanted? If this is the case, I would 
also like to clean up the above mess of having two procedures printing 
exactly the same kind of information, leading to maintenance issues.

I attached a simple diff file, so everyone could have their opinions shared.
