--- Comment #3 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- This is not redundant; the point is to convert -0 to +0. Most of the libquadmath code is generated automatically from glibc sources by substitutions done by update-quadmath.py (and most of the rest *should* be generated by such substitutions, but isn't yet), so it isn't particularly useful to report coding style issues for it to GCC Bugzilla.
