Detailed Description

Fix system bug where type ulong is not defined in linux/videodev.h on some Linux/GCC combinations.

I have found that on a Red Hat Linux 2.6.9 64 bit system with gcc 4.3.3, in order to build vidl, you need to #define __USE_MISC before #including sys/types.h and you need to make sure sys/types.h is #included in order to get ulong typedefed. ulong is used by /usr/include/linux/videodev.h which is included by several VIDL CXX files. I see some indications on the web that this ulong problem is a bug with certain Linux/GCC combinations.

This header file implements this fix. When it is needed it should be the first include.
