Looks like the function is in assembler and was never converted to C.
It used to say:

UINT32 Hash( UINT32 H )
{
        __asm {
                mov             eax,H
                mov             ebx,eax
                rol             ebx,7
                xor             eax,ebx
                mov             ebx,eax
                rol             ebx,11
                xor             eax,ebx
                mov             ebx,eax
                rol             ebx,19
                xor             eax,ebx
                mov             ebx,eax
                rol             ebx,16
                xor             eax,ebx
        }
}

I'm sure you can put together a C implementation pretty trivially.
