Tk Source Code

The ISO 99 C standard now requires that C 
compilers define bool to be _Bool.  If you want to 
use bool in your code, you have to undef it first.  
This only shows up in one place in Tk, so rather 
than fighting with the compiler, we should just 
change it.  Here is the patch (just changing the int 
bool variable to int boolval):
