Rainer Orth <ro at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Assignee|unassigned at gcc dot gnu.org |ro at gcc dot gnu.org --- Comment #3 from Rainer Orth <ro at gcc dot gnu.org> --- I'll prepare and test a patch along that line over the weekend. David, just out of interest: could you check what happens if you remove the definition of _XOPEN_SOURCE in thr.c completely? In my experience, defining feature test macros more often than not causes more trouble than it solves anything. Thanks, and sorry for the breakage. Rainer
