Does this mean I can simply put numbers like 39.37 in
the m4 output, where I was traditionally limited to integers?

Sigh. I guess I should really list the part number, since
I can't really expect all Ethernet connectors to have the
same footprint.
I just now started to play around with netlists and ratlines
in a BGA context. Things started to behave themselves after
I applied the appended patch. I don't promise that it does
the Right Thing [TM].
