2001-04-20 Correo Fernando-ruiz <correo@…>

• include/rtems/libio_.h, libc/chroot.c, libc/privateenv.c: Private environment and chroot() enhancements and fixes. Comments: + privateenv has been modified to let at chroot() to be more

POSIX like Sergei Organov recommended.

+ A task owner lets that rtems_set_private_env() will be

called twice or more times.

+ chroot() can be called without a previous

rtems_set_private_env(); (transpanrently)

+ The second call of rtems_set_private_env() makes a internal

chroot("/") into global imfs_root.

+ chroot() runs like chdir() without a previous chdir("/") with

the global root.

+ The current directory can be in a wrong place like Linux and

many other Unices.
