I've confirmed that it works, ...

  $ dd bs=1 seek=4G of=big < /dev/null
  $ (ulimit -v 10000; echo a|src/grep a big -)
  grep: big: Cannot allocate memory
  (standard input):a
  [Exit 2]

but bear in mind that my working directory is pretty hacked up: since
I couldn't get it to configure/build I pulled in bison's bootstrap
script and impatiently and recklessly chopped (removing lots of
conflicting/old/dos-related .m4 files) until everything compiled.
