[alsa-devel] alsa-drivers-HEAD does not compile against recent RHE5.1 kernels

So, if config.h is not needed in 'newer' kernels (and causes an error?),
and is needed in 'older' kernels, it is then an error to universally
include it in a configure test program where it causes an error if used
I think the error is not noticed in newer newer kernels because
init_utsname is defined in newer newer kernels. (I should look into this
statement some more.)
I think it comes down to figuring out the point between 'newer' and
'older' kernels and modifying the configure test appropriately to use or
not use config.h as required. I'm not sure how that should be done.
