Re: Release of libxml2 2.9.11

Hi, trying to build the package from the tarball on NixOS, it appears =

that fuzz/fuzz.h is missing from the archive:

testFuzzer.c:13:10: fatal error: fuzz.h: No such file or directory
   13 | #include "fuzz.h"
      |          ^~~~~~~~
compilation terminated.

It appears to be available in the git repo, so perhaps it just needs to =

be added to EXTRA_DIST or something?
