It creates a pre-processor definition (#define) such that where ever SPIF is
used in the code it compiles it as though it was: (1<<7).
Or if you mean what does 1<<7 do? Then the << is a bitwise operator in C
that shifts the value (in this case 0x01) 7 places to the left becomes 0x80.

Get yourself a decent book on C, there's plenty out there...

I am confused. What does #define SPIF (1<<7) mean? Everything else I
understand.
