Humm I may be wrong but I believe that a crucial point has been overlooked by all.

In C99 'a' is not a character but an integer character constant. The type of an integer character constant is an int which on IPL32 and LP64 platforms means that sizeof('a') = 4. See C99 Section 6.4.4.4. (I believe that C++ returns 1 but I have not tested it.)

I believe you are correct. Function calls like fgetc also return integers. They still only read 8 bits on any sane platform, just convert it to int when returning.
