Actually, installing a libmap.conf mapping libc_r to libpthread by default in 5.3 might be *less* painful than the alternative. Otherwise, an application compiled after the change that links against a multithreaded library compiled before the change might depend on both libc_r.so and libpthread.so, which would inevitably cause things to go wrong at runtime. Without a libmap.conf, it would seem that users would be forced to upgrade all of their applications and libraries that depend on libc_r simultaneously. P.S. In grepping through the next few days of -CURRENT, which I haven't read yet, it seems that someone has already been bitten by this problem. See Subject: wxgtk build error libpthred related
