From 28acfd7d9d59b37f0b1deef25be999d281c1231b Mon Sep 17 00:00:00 2001 From: Christopher Andrews Date: Mon, 4 Aug 2014 21:03:32 +1000 Subject: Added replacement stub for cstdlib atexit() funciton. This is an empty stub to simply allow use of complex types with a non global static lifetime. For more complex handling the function 'atexit' can be redefined in user code.
