If -DD redefines the "D" in the prototype as a macro D => 1 maybe that
causes problems.

Can you provide a send example program as test case? (e.g. maybe it
depends on the matrix). Perhaps you can use some printf statements to
see why it is failing to converge, comparing your compiler with GCC.

Helping to solve this svd problem would be very useful
