[Getdp] question about--with-scalar-type=complex

I just realized that I have been happily doing time harmonic calculations, using Resolutions of Type ComplexValue,
using a petsc installation that has been configured without the -with-scalar-type=complex option, obtaining however reasonably looking results,
I am wondering now - does this flag just enable a perhaps more efficient algorithm, or have I been calculating nonsense?

Any answer would be higly appreciated, as I am a little scared right now.

Actually I would be happy if everything was o.k. without that flag, because then I could continue using BoomerAMG from Hypre, which for me, up to now,
has been by far the most efficient solver,  but does not support the complex scalar type....

Best regards,
