* Alternate email is correo@fernando-ruiz.com * libc/privateenv.c: New file. * include/rtems/libio_.h, libc/Makefile.am, libc/base_fs.c, libc/unmount.c: Moved default umask, current working directory, root, and links followed count into a structure "user environment" that can then be treated as a unit. This enable giving unique copies of these to individual threads or collection of threads.
