Also, maybe useful : https://forum.dlang.org/post/ktntbwppqgbbajpbmrcf@forum.dlang.org
It is extern(C).

Clang with makefile.
As can be observed from your first post,
clang x64 does not pack all the bitields in the VTermStringFragment since the size is 24 bytes.
alignment seems to be on address size (64bits 8bytes)
Check the size of the other struct with bitfields Vterm.mode in the c program and the position of the bitfields if packed.
With that information you should be able to create a matching layout in D.

no alignment is settings from C source file.

sound like a solution, but not how to do this.
