No. It's clever enough to skip them.
But my dir contains a lot of auto created fpdoc xml files and some  
more junk from endless experiments.
OTOH it did not count the lfm files - 90kloc.

And here are the results for the mighty Free Pascal compiler:

Total Physical Source Lines of Code (SLOC)                = 198,187
Development Effort Estimate, Person-Years (Person-Months) = 51.64 (619.64)
  (Basic COCOMO model, Person-Months = 2.4 * (KSLOC**1.05))
Schedule Estimate, Years (Months)                         = 2.40 (28.77)
  (Basic COCOMO model, Months = 2.5 * (person-months**0.38))
Estimated Average Number of Developers (Effort/Schedule)  = 21.54
Total Estimated Cost to Develop                           = $ 6,975,423
  (average salary = $56,286/year, overhead = 2.40).


And here the results for fpc (excluding install):

Total Physical Source Lines of Code (SLOC)                = 1,789,257
Development Effort Estimate, Person-Years (Person-Months) = 520.40 (6,244.79)
  (Basic COCOMO model, Person-Months = 2.4 * (KSLOC**1.05))
Schedule Estimate, Years (Months)                         = 5.77 (69.22)
  (Basic COCOMO model, Months = 2.5 * (person-months**0.38))
Estimated Average Number of Developers (Effort/Schedule)  = 90.22
Total Estimated Cost to Develop                           = $ 70,298,812
  (average salary = $56,286/year, overhead = 2.40).
