I heard somewhere about 16 bit long char type on some of 64 bit systems. What is the size of char type on Intel 64 (EM64T) system?

There are two 64-bit ABIs in common use on EM64T / AMD64 systems:
charas 8 bits (see section 3.1.2).charas 8 bits (see Types and Storage -> Scalar Types).But the C standard does allow a “byte” to be larger than 8 bits, and a
charis a “byte” (in terms of the C standard) by definition; and such platforms do exist, e.g. some DSPs.
