Dear Release Team,

may I ask you to rebuild pngcheck package against to
the current version of zlib?

I'm maintainer of fitspng package having bug #1059970,
and I found that the bug is not related on fitspng itself.
Actually, it is caused by pngcheck during CI tests
verification. The current binary of pngcheck is compiled
against an old zlib yet, and needs a recompilation.

A test run under sid (as well as trixie) has revealed:

   x@trixiesid:/tmp/xxx$ pngcheck hippo.png
   zlib warning:  different version (expected 1.2.13, using 1.3)

   OK: hippo.png (139x152, 24-bit RGB, non-interlaced, 38.7%).

The string can be identified as the part of the source of pngcheck.c
(https://salsa.debian.org/debian/pngcheck/-/blob/debian/master/pngcheck.c)
which compares versions of the run-time zlib and the zlib compiled in:
    ...
    } else if (strcmp(zlib_version, ZLIB_VERSION) != 0) {
      fprintf(stderr, "zlib warning:  different version (expected %s,"
        " using %s)\n\n", ZLIB_VERSION, zlib_version);
    }
    ..
In my opinion, the test on a zlib version is greatly valuable,
although it may create doubts during those transitional phases.

Thank you,
FH
