Original description

The attached patch fixes a few things:

• compiler warnings about "delay.h has been moved" in wiring_private.h;
• various "no newline at end of file" warnings in Wiring files (maybe
  better submitted upstream?);
• implicit cast warnings in pins_arduino.c; and
• 'main.cxx' changed to 'main.cpp' in r799(?), but the Makefile wasn't
  updated to reflect this change.
