+Subject: [PATCH] Simplify & fix check for szlib encoder (#2263)
+
+Return the result rather than setting the exit code. "return" is a
+language keyword whereas "exit" is a function for which the <stdlib.h>
+header has to be included which it wasn't in this test, therefore the
+test would previously fail to identify that the encoder was enabled if
+"-Werror=implicit-function-declaration" was used, which it is by default
+with clang from Xcode 12 and later.
+
+Fixes #2262
