This seems to have caught some params as well which is not undesirable IMO.
It also caught some strings containing this which is undesirable so I
excluded them manually. (engines/sci/engine/kernel_tables.h)
The header contains forbidden symbols on some platforms, and the
simplest solution seems to be to include it here. This also includes
it from all the portdefs.h files, except the Symbian one. Probably
the FIXME and the #if can be removed once it's known to work.
