types, variable names and fields

Dear all,

Do you know whether ANSI C (or some other dialects) support the
following:
* a variable name coincides with a type name,
* a structure/union field name coincides with a type name
in the same file (.c + all relevant .h's)?

e.g.

typedef int m;

typedef struct a {
int i;
char m;
} b;

char *m
.
