--- Comment #1 from Paul Backus <snarwin+bugzilla@gmail.com> ---
Note that on some platforms there are other possible signatures for main; e.g.,

extern (C) int main(int argc, char** argv, char** envp) { ... }

@MoonlightSentinel created dlang/dmd pull request #13749 "Fix 22831 - Check signature of extern(C) main functions" fixing this issue:

- Fix 22831 - Check signature of extern(C) main functions

  Enforce that the `main` function uses (most likely) valid arguments /
  return types. The spec / C standard denotes the following signatures:

  ```d
  int main() { ... }
  int main(int, char**) { ... }
  ```

  The implemented checks are more lenient to accomodate for common
  deviations from the standards. See the DDOC comment of `checkMain()`
  for a list of accepted extensions.

  Exotic platforms that expect a different signature can circumvent the
  checks using  `pragma(mangle, "main")`.

  See e.g.
