I think I already addressed this point:

Also, the CONST_PTR macro has been unconditionally "struct type **const"
since 5.1, which admittedly is not much time.

I don't know about Microsoft C. I do know that I build Cygwin gdb
using Cygwin gcc. I don't know about djgpp.

I don't know.
The second half of the question is "and does Microsoft C still have
a problem with struct type **const".
If we do support building with Microsoft C, and if Microsoft C has
a problem with "struct type **const", then gdb 4.18, 5.0, 5.1, and
5.1.1 are all broken in one spot. Maybe that is not a good reason for
breaking it in other spots. But one instance of "struct type **const"
has been in released versions of gdb for 34 months now and I don't see
complaints coming in.
