No ... it is just fubar.
The system calls either return a single 32 bit value, a single 64 bit
value, or two 32 bit values (pipe).
You can't cast between the different return types.
For instance sparc32 will return a 32 bit value in %o0,
but a 64bit value has the high part in %o0 and the low part in %o1.
Since most system calls return 'int' the return value should be int.
To get anything else you'd need to cast the __syscall() itself to
a different function type.
