Well, you are right that sizeof is done at compile time, and it isn't
a function. But it won't return 1.

Sizeof is an operator. The thing it is operating on is a character
constant. In C, a character constant *is* an integer. Thus sizeof a
character constant must the the same as the sizeof an integer. (Now,
for the gurus: am I right in saying integer, or should I say `of some
integral type'?)
