Hi,

I'm getting the following warning while compiling with FreeBSD :

--- zlib/inflate.o ---
zlib/inflate.c:1528:61: warning: shifting a negative signed value is undefined [-Wshift-negative-value]
    if (strm == Z_NULL || strm->state == Z_NULL) return -1L << 16;
                                                        ~~~ ^

# cc --version
FreeBSD clang version 3.8.0 (tags/RELEASE_380/final 262564) (based on LLVM 3.8.0)
Target: x86_64-unknown-freebsd11.0
Thread model: posix

Thx !

Ben

I've checked-in a fix for this into git (using the same change that newer zlib versions use).
