This version of the patch just fixes up the comment to sound better.

If the user said what cross compiler they want, why not just trust him? Those lines are way too long btw.

That is how Mark prefers this change. I would like to see a -compiler_name option and just be the end of it. ./switch-arch ppc -compiler_name powerpc-elf-gcc-4.0.1 is how it would be used.

What I mean is, if the user has specified a CROSS_COMPILER, it is rather foolish to detect other toolchains (and prefer to use those, even).
The Linux kernel uses CROSS_COMPILE for this btw (note the lack of R).

So you probably prefer the first version of this patch where the select-prefix() function would return before going thru the loop.

That makes sense, or at least try what they asked for first.

Correct. I may have typoed in my suggestion for the name.
