Well, but in the case of main() the behaviour is specifically defined by
the languages standard!

My draft copy of the standard has 

  3.6.1.5 A return statement in main has the effect of leaving the main
  function (destroying  any  objects with automatic storage duration) and
  calling exit with the return value as the argument.  If  control
  reaches  the end  of  main  without  encountering a return statement,
  the effect is that of executing
          return 0;

Moreover, -pedantic is probably not what you believe it to be. :-)
>From the egcs documentation:

  `-pedantic'
     Issue all the warnings demanded by strict ANSI C and ISO C++;
     reject all programs that use forbidden extensions.

     Valid ANSI C and ISO C++ programs should compile properly with or
     without this option (though a rare few will require `-ansi').
     However, without this option, certain GNU extensions and
     traditional C and C++ features are supported as well.  With this
     option, they are rejected.
