Besides, it's silly. GCC however will generate a line number of
zero when it is pre-processing builtins for assembler-with-cpp files:
# 0 "<built-in>"
We do not want to barf on this, especially since such files are used
in the GCC and GDB testsuites. So we check for negative line numbers
rather than non-positive line numbers. */
