/* 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.
