I am using the Debian package version of PWC and I am not trying to build a new version for the kernel. I only import pwc_ioctl.h to get access to variables and information about the connected camera.
My problem is that the definition in the file (newer version) makes the compiler exit with a failure, and I cannot recompile my program without modifying PWC.

If you are using a debian kernel >=
2.6.18, pwc is already included. If you are
using >= 2.6.9 then you have a pwc-source package with small custom changes.
