+/* Because of some really cool feature in video4linux1, also known as
+ * 'not including sys/types.h and sys/time.h', we had to include it
+ * ourselves. In all their intelligence, these people decided to fix
+ * this in the next version (video4linux2) in such a cool way that it
+ * breaks all compilations of old stuff...
+ * The real problem is actually that linux/time.h doesn't use proper
+ * macro checks before defining types like struct timeval. The proper
+ * fix here is to either fuck the kernel header (which is what we do
+ * by defining _LINUX_TIME_H, an innocent little hack) or by fixing it
+ * upstream, which I'll consider doing later on. If you get compiler
+ * errors here, check your linux/time.h && sys/time.h header setup.
