Control: retitle -1 dietlibc: libpthread overrides __errno_location even with TLS enabled
I've now tracked this down: libpthread apparently overrode __errno_location to point it to td->errno, where td is POSIX thread descriptor. This is just plain wrong, because errno is now a (TLS) variable, while in ancient dietlibc versions it used to be defined as the dereference of said function. However, syscalls still use that function to set the errno, so any code checking errno would fail in that case. Once I've made sure #844781 is fixed (and no other problems have arisen in the mean time), this will be part of the next upload. Regards, Christian
