Is it necessary to nest the function to fix this problem? Are you sure
no other function will ever need str_tx_byte?
As far as I can see, the global variable is only used for communication
between the two functions, of which one is a callback.
By nesting the function, the variable can be local.
The only alternative I see is to rewrite that part entirely.
Unless the gcc maintainers plan to kill this extension, I see no reason
not to use it.
