Bug 23778 – Code generator fails to handle __c_complex_real properly for Windows

Test code: ---- enum __c_long_double : double; alias __c_long_double c_long_double; struct _Complex { c_long_double re; c_long_double im; } version (all) { // fails enum __c_complex_real : _Complex; alias c_complex_real = __c_complex_real; } else // works enum c_complex_real : _Complex; c_complex_real toNative2(real re, real im) { return c_complex_real(re, im); } void main() { c_complex_real n = toNative2(123, 456); assert(123 == n.re && 456 == n.im); } --------- The trouble is that __c_complex_real is treated specially in the compiler, and in totym() it is always replaced with TYcldouble. On Windows where long doubles are actually doubles, it should be TYldouble.
