Note that nacl_main got moved to components, I think.

I'm not familiar with this code, but bbudge did mention that at some point the
NaCl + Pepper timers on Windows would not give > 16ms timer resolution.  Would
that regress w/ this?

 #if defined(OS_WIN) || defined(OS_MACOSX) || defined(OS_LINUX)
   NaClMainPlatformDelegate platform(parameters);
 
   platform.PlatformInitialize();
   bool no_sandbox = parsed_command_line.HasSwitch(switches::kNoSandbox);
   platform.InitSandboxTests(no_sandbox);
 
 #if defined(OS_POSIX)
   // The number of cores must be obtained before the invocation of
   // platform.EnableSandbox(), so cannot simply be inlined below.

 #endif
 
   platform.PlatformUninitialize();
   return 0;
 }
