Test failures about regexp

[Xin Dong]

Hi all,

I compiled octave 3.2.2 on a x86_64 linux machine. When I run the make test, I got several failed tests related to regexp, like the following one:

  ***** assert(regexp('Iraq','q(?!u)'),4)

!!!!! test failed

regexp: Invalid preceding regular _expression_ in pattern (q(?!u))

It may not be a big deal for me, but I still want to know how to fix it.

Thanks,

Xin
