Some MSVC fixes, including (temporarily, probably) renaming the FFT source file to avoid getting it mixed up with the Vamp SDK one in our object dir

/* Unless compiled with -DNO_OVERWRITE, this variant of s_copy allows the
 * target of an assignment to appear on its right-hand side (contrary
 * to the Fortran 77 Standard, but in accordance with Fortran 90),
 * as in  a(2:5) = a(4:7) .
