--- Comment #7 from Kaveh Ghazi <ghazi at gcc dot gnu.org> --- I did the re-entrant functions (like lgamma_r) but I don't recall ever doing non-thread-safe plain lgamma etc, those that update the global variable "signgam". It's been a decade, so memory is fuzzy. Anyway I'm not sure if it's worth it so, no objections to closing this one.
