Subject: 'head -c BYTES' is non-portable.
X-Git-Tag: v1.4.0^2~39^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b26c53b0d0560d58b8222df5e889fe39eaec7ecb;p=thirdparty%2Fzstd.git

'head -c BYTES' is non-portable.

Pull request #1499 added a new test, which uses 'head -c'. The '-c'
option is non-portable (not in POSIX). Instead use 'dd'. Similar issue
has been resolved in the past (#1321).
