C has the #line directive for that (GCC doc); AFAIK Vala generates it when in debug mode.

Sounds reasonable as long as they skip the pre-processor stage, otherwise things might get rather confused. I assume that their variables map one-to-one to C variables to simplify debugging.

I don't entirely understand why they don't generate it always. GCC's own preprocessor does. If you don't, even compiler error messages will be wrong, and you want them to be right even if you're not in debug mode.
