Summary: solve/numer spurious polarform

Initial Comment:
 solve(x^2-1,x),numer
   => [x=%E^(3.14*%i), x=%E^(6.28*%i)]
same for solve(x^2-1.0,x),numer;

Why????

Mysteriously, 

  solve(x^2.0-1.0,x),numer
    => [x=1.0]

I'm informed by Stavros that the polarform is not observed
on Windows, too. Closing this report as fixed.

5.9.3cvs / sbcl, clisp, gcl (all Linux) yield

solve(x^2-1,x),numer;
 => [x = 1.2246063538223773E-16 (%i - 8165889364191922),
x = - 2.4492127076447545E-16 (%i - 4082944682095961)]

so the reported spurious polarform seems to have gone away.

Mark this report for verification on Windows -- if not
observed there we can close this report.
