Module `entrypoint`;
  DMD-generated module __entrypoint where the C main resides
Module `rootHasMain`;
  Module in which the D main is
void `genCmain`(Scope* `sc`);
  Generate C main() in response to seeing D main().
  This function will generate a module called __entrypoint, and set the globals entrypoint and rootHasMain.
  This used to be in druntime, but contained a reference to Dmain which didn't work when druntime was made into a dll and was linked to a program, such as a C++ program, that didn't have a Dmain.
  Parameters:

  Scope* `sc` | Scope which triggered the generation of the C main, used to get the module where the D main is.

int `main`();
  Entry point which forwards to tryMain.
  Returns:
  Return code of the application
void `addDefaultVersionIdentifiers`();
  Add default version identifier for dmd, and set the target platform in global. https://dlang.org/spec/version.html#predefined-versions
  Needs to be run after all arguments parsing (command line, DFLAGS environment variable and config file) in order to add final flags (such as X86_64 or the CRuntime used).
