[Tinycc-devel] Type names as identifiers

[Alex Measday]

TCC reports an error when a type name is used as a field name
in a structure.  I try to avoid this practice in my own code,
but I'm encountering it in some automatically generated C
code.  In this case, an enumeration type is declared and
its name is later used as a field name in a structure.

Here's a simple test program:

    typedef  enum  ABC {
        A, B, C
    }  ABC ;

    typedef  struct  XYZ {
        int  ABC ;            <<<==== error here!
    }  XYZ ;

    int  main (int argc, char *argv[])
    {
        XYZ  xyz ;
        xyz.ABC = 1 ;
        return (0) ;
    }

TCC reports: "test.c:6: identifier expected"; GCC compiles it without
error.  ISO C99, Section 6.2.3, #1 seems to allow it when it says "each
structure or union has a separate name space for its members".

Thanks,
