without main

Although its not possible to write a program without main() but still it may be possible that main() is not present explicitly... as follows:

#include
#define decode(s,t,u,m,p,e,d) m##s##u##t
#define begin decode(a,n,i,m,a,t,e)
begin()
{
printf("Stumped??\n");
}


But main() is indirectly present.
