+Subject: [PATCH] exim_lock: fix lstat-related build errors
+
+exim_lock fails to cross-compile with the Sourcery CodeBench ARM 2014.05
+toolchain due the a missing include of sys/types.h, needed for the
+constants used by fstat() and lstat().
+
+Discovered when cross-compiling with the Buildroot embedded Linux
+buildsystem.
+
+Fixes:
+

+         if ((statbuf.st_mode & S_IFMT) == S_IFLNK)
+                                ^
+  exim_lock.c:427:30: note: each undeclared identifier is reported only once for each function it appears in
