------- Comment #28 from carlos at codesourcery dot com 2009-04-28 20:57 ------- Exporting a non-default versioned symbol is useless since new programs won't be able to link against that definition.
Did 4.2/4.3 export a global default symbol for __signbitl? If we did export a global default symbol for __signbitl then we must continue to export it. The current glibc math.h signbit macro will evaluate to __signbitl if passed a long dobule type, and therefore correct programs using the signbit macro may have ended up referencing __signbitl from libstdc++.
