+    Fix the build with glibc 2.16
+    
+    With our elevated compiler warnings as errors, we got:
+    
+      mainloop.c: In function 'stp_main_loop':
+      mainloop.c:581:3: error: signed and unsigned type in conditional expression [-Werror=sign-compare]
+      mainloop.c:581:3: error: signed and unsigned type in conditional expression [-Werror=sign-compare]
+      mainloop.c:583:35: error: signed and unsigned type in conditional expression [-Werror=sign-compare]
+      mainloop.c:583:35: error: signed and unsigned type in conditional expression [-Werror=sign-compare]
+      mainloop.c:631:2: error: signed and unsigned type in conditional expression [-Werror=sign-compare]
+      mainloop.c:631:2: error: signed and unsigned type in conditional expression [-Werror=sign-compare]
+      cc1: all warnings being treated as errors
+    
+    This turns out to be a macro fight between glibc-2.16 and
+    kernel-headers, via including linux/types.h.  We apparently don't
+    even need that header, so removing it lets us proceed normally.
+    
+    Those curious can watch this bug to see how the conflict is resolved:
