There seems to be a typo in your example -- it won't parse. I tried
ineq:... instead of ineq=..., and tried removing ineq=, but that yields an
error from solve_rat_ineq. Tested in Maxima 5.28.0 and 5.30.0 / SBCL / OSX
/ wxMaxima. Also, "==" (in your output) is not a standard Maxima operator
(does a newer version of solve_rat_ineq define it?).
* What is the exact input you used?
* What is the version of Maxima you used?
* Are you using the version of solve_rat_ineq that came with Maxima, or
some other version?
