Hmm, doesn't that defeat the whole purpose of error messages?
I mean, by this you are HIDING the error messages, too. The current problem 
with the make output is that a plethora of useless progress messages are 
hiding those few error messages that would be really useful to be seen.

Hiding all error messages together with the progress messages is throwing out 
the baby with the bath water (as we say here in German).

To me, the whole aim of reducing the make output is to:
-) Reduce the progress messages, so that:
-) Error messages are shown more prominently,
-) While there are still enough progress messages to see the context of the 
error

I.e. when a file fails to compile, ideally the output would still show the 
error message and before that the progress message which file was processed 
(in particular, also the path, since we have files with similar names in 
different directories!!).

Cheers,
Reinhold

PS: On my server, for the nightly doc builds, I have long ago decided to pipe 
the output to /dev/null, since if there is an error, I simply can't wade 
through thousands of lines (since I'm doing a parallel build with CPU_COUNT=2 
and -j3, the progress messages of different files are even interspersed, 
making them even more useless!) to find the error. And the thousands of 
progress messages also prevent me from simply sending the last ~100 lines of 
the output as the result of the cron job via email, if the make command fails.

So, if the docs fail to build on kainhofer, I probably won't even notice (and 
even if I do, I won't try to find the problem and fix it).
