Hi Andrew, > As Heinrich noticed, gmtime, strerror, and strtok are non-thread-safe
Checking the online MSDN documentation, I see that strtok is also safe on Windows for multiple threads, but It isn't clear what happens for strerror - it is implied that a pointer to a fixed string is returned but there is no explicit mention of threads. That being said, I think it is better to use the _s functions on windows, so that linking will fail in old version where there may be issues. > The problem I > encountered is that gcc (Debian 4.7.2-5) 4.7.2 installed on my Linux > machine doesn't have gmtime_s, strerror_s, and strtok_s. My understanding is that it is unlikely that a version will be provided by glibc. > It is unclear > what to do if no thread-safe version of these functions are available. I think that configure should check for the posix versions or the windows versions and fail if not found when TLS is set. I can prepare a patch for this, but I can only test it on Linux.
