In libc_r, rename vfork syscall to _thread_sys_vfork and make vfork an alias to fork. It is difficult to do real vfork in libc_r, since almost every operation with file descriptsor changes _thread_fd_table and friends. popen(3) works much better with this change. 1998-09-12 22:03:20 +00:00			`#include <unistd.h>`
