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
