I would have liked to come up with a PR, after carefully reading the PR description decision, let's mention an issue first If you don't feel the need msvc support(nelua some generate c code unable to compile), just turn close this issue.

You should try using MSVC Clang if that is an option for you. Then you don't need to do anything. I am afraid the cl compiler doesn't support all features Nelua need, you could check by running the test suite. Nelua may occasionally generate C code using extensions such as https://gcc.gnu.org/onlinedocs/gcc/Statement-Exprs.html that only GCC/Clang supports AFAIK. (See also https://github.com/edubart/nelua-lang/discussions/73)

That is interesting, but not sure if I want to add that officially, unless everything is working good. I really want to encourage just using the Clang/GCC frontend.

@edubart Statement-Exprs are more problems, need to redo cgenerator, I'll close this issue.
