matlab compability of str2func

[Norbert Froehlich]

Bug report for Octave 3.0.3 configured for i686-pc-msdosmsvc

Description:
-----------

  When I execute the following code in Matlab I get a correct function  
handle, but not in octave.

> f = str2func('>=');

The error message in octave is:
error creating function handle "@>="

Repeat-By:
---------

   f = str2func('>=');

Fix:
---

   Change the lookup of the function?
