            Bug ID: 3392420
           Summary: Incorrect dependency generation in -MD flag
           Product: NASM
           Version: 2.13.xx
          Hardware: All
                OS: All
            Status: OPEN
          Severity: normal

Simplified example source code

Platform is MSYS2 (no idea if patches were applied). Package
"mingw64/mingw-w64-x86_64-nasm 2.13.01-1" is installed.

With the attached files (purposely reduced), running:
nasm -f win64 <OPTIONS> test.d -o /dev/null test2.asm && cat test.d
results in:
- with <OPTIONS>="-MD", "nul: test2.asm"
- with <OPTIONS>="-M -MF", "nul: test2.asm test1.asm"
Only the second output is valid.
Larger, more meaningful commands and source code are equally affected.

To summarize, -MD doesn't seem to properly output all dependencies, in
particular those due to %include.
