Rule 3.5: bitfields and basic types

[Reggi]

Hi,

i have a question about the type in bitfields.

In the example in rule 3.5 there is the note \"Note: use of basic types is required\"

In rule 6.3 it says: \"typedefs are not considered necessary in the specification of bit-field types.\"

So typedefs are not forbidden for bitfields.

I don't anderstand the stätement in the example of rule 3.5.

Why are basic types required here?

Do you have an explanation, why i should write

unsigned int x_set:1

and not

uint32_t ? x_set:1?

Thanks,
Regine
