cdecl16far calling conventions incorrectly return 4-byte value

Describe the bug I create functions with the calling convention _cdecl16far, which returns a 32 bit value (dword, long, char * 32) the result is declared as register AX: 2 (ntr) and the value on the stack. The code shows that the result is transmitted by registers DX: 2, AX: 2 If you select the calling agreement as cdecl16near, then the result is declared correctly DX: 2, AX: 2

To Reproduce Steps to reproduce the behavior:

1. Open WIN16 exe file
2. Select function, "Edit Function Signature"
3. Calling Convention __cdecl16far
4. Datatype char*32

Expected behavior Storage DX:2,AX:2
