Hi,

I've been updating the cpia V4L driver distributed from sourceforge as
a replacement for the kernel version (needed until all the 
accumulated enhancements make it into the kernel - hopefully in 2.4.21).

The sourceforge version is full of preprocessor instructions such as,
in particular (now)

#if (LINUX_VERSION_CODE >= KERNEL_VERSION(2,4,19))
#define NEW_V4L_INTERFACE 1
#endif

Here's my problem:  The 2.4.19 changes break 
hot-unplugging code that uses the old interface.
But they are also present in the 2.4.18
kernels used by RedHat 7.x

Is there any way the preprocessor could detect
the changed interface?  (or RedHat patching)

(I didnt see  any 
#define V4L_VERSION xxxx
in videodev.h)
