Empty structs are now (correctly) invalid. The hack of using an empty
struct to represent a handle returned from a builtin has been unnecessary
since opaque structs were implemented: now a pointer to an opaque struct
can be used. This is mostly safe as handles are aways negative and thus
attempting to dereference such a pointer should result in a VM error. It
will be even safer once const is implemented and the pointers can be made
constant (eg, typedef struct handle * const handle;)
With this, ruamoko/lib almost compiles (though no object files are output).
Just some bogus "redeclared" errors and an improperly implemented
statement that produces an ice.
This is an extension "wrapper" (no such C function). This allows ruamoko
programs to read property lists without worrying about the memory required
to store the string for the property list being read.
Much more testing is required (oh, but for qc-valgrind), but there is now
a ~945kB block of free data in the menu progs heap :).
Also, correct the printed size of the memory block to not include the
block header size.
