* argp/Makefile (routines): Add argp-eexst.
* argp/argp-ba.c (argp_program_bug_address): Make `const'.
* argp/argp-eexst.c: New file. Define exit status variable.
* argp/argp-help.c (__argp_state_help): Use argp_err_exit_status
variable instead of always exiting with value 1.
* argp/argp-pv.c (argp_program_version): Make `const'.
* argp/argp.h: Declare argp_err_exit_status.
Patches by Miles Bader <miles@gnu.ai.mit.edu>.

switching of UID before opening .rhosts.

proposal. The return value now is always the number of characters
which would be written if enough space is available.
