The sizeof operator returns a value that is of type size_t. The
definition of size_t is implementation dependent, according to the
ANSI standard. In Microsoft C, the size_t type is defined in STDDEF.H
and in MALLOC.H as an unsigned int. This is documented on Pages 38 and
98 of the "Microsoft C Optimizing Compiler Run-Time Library Reference"
manual.

The reference manual describes the sizeof operator on Pages 120-121,
Section 5.3.4, but does not give the return type.

The index entry for "size_t type" incorrectly lists Pages 38 and 97;
it should say 38 and 98.
