Would it be possible to add a GNU coding style?  The full style description for the GNU coding conventions is at http://www.gnu.org/prep/standards/standards.html#Writing-C.

Out of those conventions, I think these are the more prominent ones:

- Line length is 80 columns.

- Open brace for a function body is always in column 1.
- The name of the function is always at column 1.
The above two rules mean that function definition 'int foo(int x, int y) { ... }' must be formatted as:

int
foo (int x, int y)
{
  ...
}

- There must always be a space between a function name and the open parens. So, it's "foo (x, y)", never "foo(x, y)". Yeah, I hate it too.

- Open braces for structs/unions can be on the same line or column 1.

- There is always a space after a comma.

- Braces always go on the next line, indented by 2:

int
foo (int x, int y)
{
  while (x < y)
    {
      do_something_with (x);
      x++;
    }
  return x;
}

- When splitting expressions into multiple lines, split BEFORE the operator:

  if (this_is_a_very_long_predicate
      && x > this_other_value)
    {
      ...
    }

- do-while statements are formatted like:

  do
    {
      ...
    }
  while (...);


Thanks.
