To handle global C++ constructors, and because it can't modify crt0 on
any given machine, GCC automatically inserts a call to __main() inside
a program's main().  If you use `gcc' to link the program, it will also
automatically include libgcc.a, which has a default __main().

__main() calls each constructor in turn and uses atexit() to register a
procedure will calls all the global destructors.
