implement robust mutexes some of this code should be cleaned up, e.g. using macros for some of the bit flags, masks, etc. nonetheless, the code is believed to be working and correct at this point. 2011-03-17 20:41:37 -04:00			`#include "pthread_impl.h"`

make pthread attribute types structs, even when they just have one field this change is to get the right tags for C++ ABI matching. it should have no other effects. 2013-07-22 13:57:02 -04:00			`a->__attr &= ~4;`
