Ok, and what about LIPSOL?
As far as I understand from
http://plato.asu.edu/ftp/lpcom.html
LIPSOL       linprog in Matlab 7.0
lipsol is used in  MATLAB linprog
it's homepage is
http://www.caam.rice.edu/~zhang/lipsol/
and all links say LIPSOL if free.
Since it has connection to MATLAB (as his homepage says) I guess integrating
it to Octave will be not too hard.
So what do you think?
