Completely standard and should work in every platform. The only
non-standard thing is the fixed address, that will be platform-dependent.
There are (not much) clearer ways to write it though:

typedef void (*functionpointer_t)( void );

#define myfunc() ( (functionpointer_t)0x4ff0 )()

....
myfunc();
....
