Projekt na ukończeniu, przed chwilą wszystko działało. Wprowadzałem pewne poprawki do kodu, przy czym zdecydowana większość dotyczyła zupełnie innego pliku źródłowego. W kodzie odpowiedzialnym za obsługę komend zmieniłem zaledwie kilka linijek w pewnej procedurze.
Próbuję skompilować i niespodzianka... Atmel Studio sypie błędami i warningami, ale nie tam, gdzie coś zmieniałem. Czepia się fragmentu, który jeszcze chwilę temu nie sprawiał żadnych problemów problemów.
Błędy wyglądają następująco:

Treść pliku komendy_at.c:
[syntax=c].................[/syntax]
NIE UMIESZCZAMY NA FORUM CAŁYCH BIBLIOTEK Z KSIĄŻEK ANI ICH FRAGMENTÓW - Sonix
Ktoś mi powie co może być nie tak? Sytuacja mnie zaskoczyła i nie mam zielonego pojęcia co zrobić z tą sytuacją...
Czy coś przez przypadek zmieniłem? Jeśli tak, to co?
W przypływie desperacji spróbowałem nawet poprzenosić poszczególne pliki źródłowe do nowego projektu. Nie pomogło...
UPDATE:
Właśnie zauważyłem, że jeśli tylko umieszczę całą treść biblioteki komendy_AT w komentarzu, to taki sam zestaw błędów pojawia się w następnej bibliotece.
Występuje jedna prawidłowość - czepia się do zmiennych extern...
UPDATE2:
Wychodzi jednak na to, że dodane biblioteki coś psują w kodzie. Po ich odkomentowaniu wszystko się kompiluje.
Poniżej treść kłopotliwych plików:
