Feisty videodev.h dependency errors

Bug Description

I was trying to compile some software called luvcview. It compiles OK in Edgy, but there seems to be a regression under Feisty beta.

You can see dependency problems by creating the file blah.c:

#include <stdio.h>
#include <videodev.h>

main()
{
puts("hello");
}

Then do
gcc -I/usr/include/linux blah.c

You'll get:
In file included from /usr/include/_G_config.h:44,
                 from /usr/include/libio.h:32,
                 from /usr/include/stdio.h:72,
                 from blah.c:5:
/usr/include/gconv.h:72: error: expected declaration specifiers or ‘...’ before ‘size_t’
...

luvcview now compiles on Feisty.

However, _G_config.h still doesn't find size_t. Technically, I think think that this is still "wrong", but now a low-priority bug as far as I'm concerned.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with latest Ubuntu release? Thanks in advance.

blah.c Edit (83 bytes, text/plain)

Nanley, it's not so much of an issue now, I can get to compile what I want to compile. I still think there's a bug, though - that is better ironed out instead of being closed.

I am now using Gutsy, with my packages up-to-date. My original code was slightly flawed, and a better version (also attached) would be:

#include <stdio.h>
#include <linux/videodev.h>

main()
{
puts("hello");
}

... note that I included linux/videodev.h instead of just videodev.h. This allows for a cleaner compilation command:
gcc blah.c

The error I get is now:

In file included from /usr/include/linux/videodev.h:15,
from blah.c:2:
/usr/include/linux/videodev2.h:482: error: field ‘timestamp’ has incomplete type

I would therefore like to maintain the stance that there is still a bug which needs sorting out. There is obviously some kind of dependency problem with the include files.

It compiles cleanly on my Hardy with just build-essential installed.
