Don't do this here.  It could be in a constructor (i.e. a function someplace
like irt_ppapi.c with __attribute__((constructor))).  But better would be to
have this done only as needed, i.e. on the first call to the manifest loading
stuff.

I implemented this as a constructor.

+    static const char fatal_msg[] =
+        "ppapi initialization (PpapiPluginPreInit) failed.\n";
+    write(2, fatal_msg, sizeof(fatal_msg) - 1);
+    _exit(-1);
+  }
+#endif

   /*
    * Call the user entry point function.  It should not return.

   (*user_start)(info);
 
   /*
    * But just in case it does...
    */
   _exit(0);
 }
 
 /*
  * This is never actually called, but there is an artificial undefined
  * reference to it.
