Hi!
The problem is that MySQL will not work without a Posix library, so
it isn't that easy to fix this. In any case, linuxthreads is better
than mit-pthreads on Linux, so we don't have that many options here.
The best I can do is to add some documentation that if one uses
Slackware 4.0, one should upgrade to glibc 2.1 before starting to use
MySQL under heavy use or if one uses a dual pentium box.
Regards,
Monty
