Rule 5.6 A ty pedef name shall be a unique identifier

[xiaoxin]

My doubt about this rule is if they violate rules in different files, as follows.If they violate the rules in the same project.
a.c

Code:

void func ( void )
{
    {
        typedef unsigned char u8_t;
    }
}

b.c

Code:

void func ( void )
{
    typedef unsigned char u8_t;
    â€¦â€¦
    
}

Similarly, there are rules 5.3 : An identifi er declared in an inner scope shall not hide an identifier declared in an outer scope
c.c

Code:

int a =8;

d.c

Code:

void main(){
int a = 9;
}

In other words, whether cross-document considerations are considered。
Looking forward to your reply。
