[tldistro] zlib-1.2.6 and XeTeX

[Peter Breitenlohner]

Hi,

as has been noted by Dan Ports (drkp at csail.mit.edu) XeTeX used to fail to
load formats when built with a system zlib-1.2.6.

The current TeX Live SVN sources (r25386) now contain zlib-1.2.6 and the
code in XeTeX is changed such that it requires zlib-1.2.6 and fails with
zlib-1.2.5 or earlier.

Conclusion: when using --with-system-zlib for the old resp. new version of
XeTeX you must use a zlib version <=1.2.5 resp. >= 1.2.6, not only when
building XeTeX but as well when running the program.
