--- Comment #13 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Roman Fietze from comment #12) > Sorry if it is inappropriate to ask for any changes, but how can it be, that > there is no fix for this bug for years in any of the GCC releases? Because it's not possible to implement the C++ requirements purely in terms of POSIX, so it requires a new API in the C library, which is complicated. All the information you need to investigate that is provided in this bug report and the enclosed links. > With this bug condition_variable::wait_until is completely unusable on many I find that hard to believe.
