Windows Store and Xbox One apps need to pass WACK, the Windows App Certification Kit, and part of that process involves a tool named BinScope that checks the debug info of all object files making up the final executable against a list of minimum versions. These minimum versions get increased periodically as new SDKs and compilers are released. In a patch 2 years ago, I made NASM pretend it was MASM and output a then-current MASM version number. Well, the minimum version number has increased again, and periodically hardcoding a new random MASM version to keep BinScope happy doesn't seem like the way to go. It turns out that BinScope does not impose any minimum version requirements on object files listing a source language BinScope doesn't know about. I have no idea how to officially request a new CodeView language ID (or whether there even is a way to do so for someone outside MS). But experimentally, using 'N' (0x4e) for NASM seems to be working just fine and is far away from the range of currently allocated language IDs (which stop at 0x10). Long story short, make NASM emit a source language ID of 0x4e, with the actual NASM version in the version number fields. BinScope is happy to accept that, and since the language ID field is purely an informational field in an optional debug info record that (as far as I can tell) is not used for anything else, this seems reasonably safe and unlikely to cause trouble.

NASM, the Netwide Assembler.
Many many developers all over the net respect NASM for what it is
- a widespread (thus netwide), portable (thus netwide!), very
flexible and mature assembler tool with support for many output
formats (thus netwide!!).
Now we have good news for you: NASM is licensed under the "simplified"
(2-clause) BSD license. This means its development is open to even
wider society of programmers wishing to improve their lovely
assembler.
The NASM project is now situated at SourceForge.net, the most
popular Open Source development site on the Internet.
