No, it's not.  Again, fprintf(stderr)+fflush *does* work, I've been
using various times.  If you don't get your prints going somewhere,
you're probably not managing to start your rebuilt programs.  Again, to
be sure, put fprintf(stderr)+fflush in the main() and initialization
function of your translators and libraries to make sure you're really
running what you want to be running.

mach_print can't do that. Mach doesn't even know what a file is.
