No, not at all. "--output-only-errors" would cause all output to be 
dropped on the floor.

E.g.

.PHONY: foo bar
.DEFAULT: foo bar
OMakeFlags(--output-only-errors)

foo:
    echo This is foo

bar:
    echo This is bar
    exit 1

would only print "This is bar", but would drop "This is foo".

Good point! Care to file a Bugzilla entry to make sure this is not 
overlooked?

Thanks!
