Again, I have found that information to be useful on numerous occasions. Also, considering how noisy the whole ICU build is, I think the extra clutter for parrot's sources is not a significant additional burden.
I don't like the change, it just hides all warnings. Further "make -s" just broken now.
While building ICU is noisy, it doesn't mean that building parrot should be as noisy or even more.
But I see of course the point of beeing able to see the current build command. What about that: cc_flags.pl prints the build command if it changes, i.e. if there are any changes except the filename(s) involved.
