I think <complex> is the ANSI draft standard header.  The standard
also allows <complex.h> for compatibility reasons.  One is a wrapper
around the other, and the contents are the STL "complex" definitions.

The old <Complex.h> (<_complex.h> in DOS) is non-ANSI standard by now,
and DJGPP's <_complex.h> merely #include-s <complex> and typedefs
Complex as complex<double>.
