* pthread_cond_destroy.c: Expand the time change
critical section to solve deadlock problem. * pthread.c: Add all remaining C modules. * pthread.h: Use dllexport/dllimport attributes on functions to avoid using pthread.def. * sched.h: Likewise. * semaphore.h: Likewise. * GNUmakefile: Add new targets for single translation unit build to maximise inlining potential; generate pthread.def automatically. * Makefile: Likewise, but no longer uses pthread.def.
