OK, I have 2 nonideal solutions. The first is a 1-line script wrapper around bc:

dosbc:
------
#!/bin/bash -i
dos2unix | bc

The second is to use the open source math package Octave, which doesn't seem to trip over the DOS line endings. To bang out from vim, however, I need to suppress the splash message and complaints about X11 not being set up:

alias octxt='octave --no-window-system --silent'
