imo, it's a bug in unifdef.  it is declaring its own function named "getline" 
which clashes with the glibc one.  it might depend on the compiler flags used 
(_GNU_SOURCE or something), but it's still poor taste i think and simpler to 
just change the name in the code.

either way, this should be on lkml
