+Subject: gzexe: use -C if lacking mktemp
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+(Problem reported by Michał Majchrowicz.)
+* gzexe.in: If mktemp is needed but not installed,
+use ‘set -C’ to avoid a race when creating a temporary file.
+* zdiff.in: Use the same pattern here, even though the old
+code was probably OK anyway.
