 Both of these are due to the expanded $Date$ at the bottom of the file.

 I don't know what happened to your comment (cut/paste issue?), but this
 should read:
 {{{
 main.c: In function `drain_cost':
 main.c:697: error: `dir_name' undeclared (first use in this function)
 }}}
 Indeed, dir_name is local to main(), so it isn't visible in drain_cost().
