[boost] [thread] #2739 shouldn't at_thread_exit work on the main thread?

Hi, Anthony, I have submitted a patch that makes a regression on the test test_tss. My patch was related to add a atexit call for the main thread when make_external_thread_data is called, but it adds also for the thread created with native threads. So the patch don't work. Is there a way to make a difference between the main thread and the others? BTW the test fails on cygwin gcc 3.6.4, could someone test it on Windows or Linux to see if this is specific to cygwin?
