+# A name missing from this list is not a warning, it is a FAILED RELEASE: the
+# bundler hunts for it in the MinGW sysroot, does not find it (it only exists
+# on Windows), and exits 1. That is how DWrite.dll broke a setup-pack job --
+# recomp-ui's Win32 emoji/font path imports DirectWrite, Direct2D and WIC, and
+# none of the three was listed. When a new import shows up here, ask whether
+# Windows ships it before reaching for a copy of it.
