On HP-UX 11.31/hppa, I'm seeing this compilation error:
cc: "../../gltests/test-uchar.c", line 33: error 1511: Bit-field size must be a
constant.
cc: "../../gltests/test-uchar.c", line 33: error 1613: Zero-sized struct.
cc: "../../gltests/test-uchar.c", line 33: warning 504: The sizeof operator
applied to a zero-sized object.
The char32_t is correctly defined. It looks like the compiler has a
problem with casted values in constants.
