The script doesn't know about all possible types and learn them as
it parses the code. If it reaches a line with a type cast but the
type isn't known yet, it is misinterpreted as an identifier.
For example the following line:
foo = (hwaddr) -1;
results in the following false-positive to be reported:
ERROR: spaces required around that '-' (ctx:VxV)
Let's add this standard QEMU type to the list of pre-known types.
