Still present. Could one of our x86 experts review Pete Eberlein's patch from
2006?
Testcases are certainly needed for libm-test.inc for a fix to go in - both
tests for the particular cases here, and tests for more normal cases of powers
of negative numbers (negative number to small (+ve and -ve) even powers,
negative number to small (+ve and -ve) odd powers). Cases involving infinities
and zeros as arguments seem better covered in the testsuite and there are
already tests of negative numbers to fractional powers.
