How to use extern sbit declare?

I declare a variable unsigned char bdata Kde in a.c.

[in file a.c]

unsigned char bdata Kde;

Than I want to use the variable inb.c.
[in file b.c]
#include <stdio.h>
.....
extern unsigned char bdata Kde;
sbit testbit=Kde^1;
void main(void)
{......}

:error C141:.......a.c:syntax error near 'sbit'

why?

    Is it the compiler's job to make my life easier? Of course. And this is a fine distinction between the preprocessor and the compiler, in more general usage the preprocessor IS (a part of) the compiler. I don't need a preprocessor/compiler to ignore the fact that I've used a duplicate label, I need it to optionally give me a warning.

    I looked for a lint utility, and it seems that the C51 lint here on the Keil website is dated 1996. What would you recommend?

    Thanks,
    Robert
