Take a look at the output of './configure --help':

  --enable-dvb             enable DVB support (must supply header directory)
  --dvb-path=HDRLOC        location of directory containing
                           'linux/dvb/frontend.h', not the
                           directory with frontend.h 

Seems to indicate giving a path into the kernel source like that doesn't work, 
as it somehow pulls in other kernel headers to the build that override glibc 
headers. Dunno if you can make that include path more specific for dvb 
components only, or if building w/an external dvb source tarball is best 
(which is what the ATrpms packages do).

The second error, I'm not sure what's going on. I thought I'd fixed all of 
those problems in the 0.18 branch. One sec while I try a build... Yup, just 
built fine. Could be a difference caused by your using the latest dvb source 
versus my using the older dvb snap Axel is currently using in the ATrpms 
packages, seeing as how scanwizard is dvb-specific. I dunno though.
