Hi Jacob,

Thanks for your remark.

In C, you can declare a variable several times, if the identifier has some linkage.
This means that if "char var1" is a global variable, you can declare it several times -- but not if it is a local variable.

So:

char var1;
char var1;
bit var2;
bit var2;

Is perfectly legal C. (I am surprised about your "The compiler flags this" comment. I verified that our compiler does NOT flag it).

However, it is allowed only for declarations, not for definitions.

char var1 = 2;  // First definition of var1
char var1 = 2;  // Second definition of var1 => ERROR

And also, you cannot have several declarations for local variables in a function.

So in brief, the code you submitted is perfectly legal C (excepted that the "bit" type is an extension to the standard), and the compiler has the appropriate behavior.

Let us know if you have an issue with this.
Regards,
Bruno
