Mini-patch for cccp.c

[Thomas Koenig]

Here's a mini-patch to cccp.c.

Rationale:

- system_header_p as char saves no space, since the struct gets padded
  anyway

- It may slow down processing infinitesimally (converting to/from int)

- using chars as Booleans are a bad idea, anyway

- This patch shuts up a spurious warning by checkergcc (which is why I
  did it in the first place)

Hope I don't have to sign a copyright assignment to the FSF for this
one-liner :-)
