[Voted into the WP at the February, 2012 meeting;moved to DR at the October, 2012 meeting.]

Proposed resolution (August, 2011):

Change 6.10.3.1 [basic.start.main] paragraph 2 as follows:

...All implementations shallallow bothof the following definitions ofmain:

  int main() { /* ... */ }

and

  int main(int argc, char* argv[]) { /* ... */ }

• function of() returningintand

• function of(int, pointer to pointer tochar) returningint

as the type ofmain (9.3.4.6 [dcl.fct]. In the latter form, for purposes ofexposition, the first function parameter is calledargc andthe second function parameter is calledargv, whereargc shall be the number of arguments...

The specification of the forms of the definition ofmainthat an impliementation is required to accept is clear in C99 thatthe parameter names and the exact syntactic form of the types canvary. Although it is reasonable to assume that a C++ implementationwould accept a definition like

    int main(int foo, char** bar) { /* ... */ }

instead of the canonical

    int main(int argc, char* argv[]) { /* ... */ }

it might be a good idea to clarify the intent using wordingsimilar to C99's.
