+Subject: [PATCH] Do not define ESTALE in config.h.in
+
+In ccache, `config.h` is included by the `-include` compiler option,
+which means that it is included before any libc headers. This doesn't
+cause any problems on systems that redefine this macro when libc headers
+are included, but on Serenity, it breaks our definition of the
+`ErrnoCode` enum.
