An excellent idea, but you happen to be in the Sun world, and you're running
Sunos 4.x, and you do this, you get hundreds of brain-dead idiotic warnings
from cc about 'file with unknown suffix .po passed to ld'; not that it doesn't
work.  I mean, *I* know what the file is, *unix* knows what the file is
by looking at the magic number, which ld BETTER DO ANYHOW, on Unix we gotta
depend on file extensions to tell us what a file is?, gotta wonder what kind
of underworked enthusiast at Sun put that inspiration in.
