Problem: When NCVT = NRU = NCC = 0 (no singular vectors requested),
BDSQR calls the dqds algorithm. If dqds failed with INFO = 1 or 3,
the routine returned immediately with that error, even though the
standard QR algorithm could still compute the singular values. Only
INFO = 2 triggered the fallback.
Change `IF( INFO .NE. 2 ) RETURN` to `IF( INFO .EQ. 0 ) RETURN`
after the dqds call, so the standard QR fallback runs on any
dqds failure (INFO=1,2,3) and not only INFO=2.
Closes#242
With MinGW the build fails for some LAPACKE xgesvd routines with:
lapacke_cgesvdq.c:74:5: error: aggregate value used where an integer was expected
Seems the C2INT macro is useful there.
