 From the release note for current gcc-g++ 12.4.0-3 at
https://cygwin.com/pipermail/cygwin-announce/2024-July/011866.html:

The D compiler had to be removed again since the runtime library still
doesn't build on Cygwin, however it's become mandatory for bootstrapping
the compiler.  If you want to work on this you need to keep the gcc-11.5
version installed.

I read that as: D is not functional with gcc 11.5, but you need 11.5 to 
work on making libgphobos buildable on Cygwin.  An exercise for the 
reader, in other words.
HTH,
