c Warning[Pe188]: enumerated type mixed with another type

I got the warning:

Warning[Pe188]: enumerated type mixed with another type

at: 

ErrorFlag = (CurrentTime - TimerX > TIMEOUT_X);

but the warning is gone if I replace it with:

if(CurrentTime - TimerX > TIMEOUT_X)
{
  ErrorFlag = TRUE;
}

Whats wrong with the first method to set ErrorFlag?

Edit:

I have a local enum:

typedef enum{
   FALSE = 0;
   TRUE= 1;
}BOOL;

and ErrorFlag is of type BOOL.

According to C11, chapter §6.5.8 (emphasis mine)

Each of the operators < (less than), > (greater than), <= (less than or equal to), and >= (greater than or equal to) shall yield 1 if the specified relation is true and 0 if it is false.107) The result has type int.

Which may not be the same type as TRUE, which seems to be an enum value local to your code.
