Which version of sane? 1.0.10-pre2? The line numbers don't seem to
match. They even point to empty lines(?)

I can't reproduce that with gcc 3.0 or gcc 3.2 on i386.

The line directive ("#line ...") is used by gcc internally so i would
call that warning an internal warning. The compiler complains about
its own preprocessor. That warning should go away if you don't use
"-pedantic".

I guess we can simply ignore these warnings.
