Description Jim Gettys 2004-02-25 10:18:44 UTC
Most people have zlib as a shared system library.

X should be using them in preference to one from in tree by default.

This needs to be release noted, with a version information.
Comment 1 Mike A. Harris 2004-02-27 15:37:02 UTC
Indeed, we should determine what all platforms come with zlib, and default
them to using the system supplied zlib.  In the past, we've had to do extra
X security erratum due to X including it's own zlib, when security holes
were found in zlib.

It's possible the defaults might actually be sane now also, definitely need
to investigate.  Small effort required.  Will update status later.
