+Subject: [PATCH] posix: don't use LFS64 types in struct linux_dirent64
+
+The *64_t types are transitional APIs for applications that do not yet
+fully support large files on 32-bit platforms.  They have been removed
+in musl 1.2.5, which caused gpgme to fail to build.  Since this is for
+a raw syscall anyway, it doesn't make sense to use libc-specific types
+here anyway, so I've changed this to match the definition of the
+struct used in the kernel (except there the kernel-specific u64 and
+s64 typedefs are used instead).
