+Subject: [PATCH] Return code 0 when builddir is already configured
+
+This is a regression in Meson 0.48.0, commit 674ae46, Meson used to
+exit(0) when running setup command in a builddir already configured.
+Changing to exit(1) breaks some build tools that does "meson builddir
+&& ninja -C builddir".
+
+Closes #4247.
