* pwdgrp.h (pwdgrp_check::pwdgrp_state): Replace by
pwdgrp_check::isinitializing ().
(pwdgrp_check::isinitializing): Create.
* passwd.cc (grab_int): Change type to unsigned, use strtoul and
set the pointer content to 0 if the field is invalid.
(parse_pwd): Move validity test after getting pw_gid.
(read_etc_passwd): Replace "passwd_state <= " by
passwd_state::isinitializing ().
(internal_getpwuid): Ditto.
(internal_getpwnam): Ditto.
(getpwent): Ditto.
(getpass): Ditto.
* grp.cc (parse_grp): Use strtoul for gr_gid and verify the validity.

group_state::isinitializing ().
(internal_getgrgid): Ditto.
(getgrent32): Ditto.
(internal_getgrent): Ditto.
2002-12-10 Pierre Humblet <pierre.humblet@ieee.org>
* security.h: Move declarations of internal_getgrent,
internal_getpwsid and internal_getgrsid to pwdgrp.h.
* pwdgrp.h: Declare internal_getpwsid, internal_getpwnam,
internal_getpwuid, internal_getgrsid, internal_getgrgid,

rather than to uninitialized.
(pwdgrp_read::gets): Remove trailing CRs.

(read_etc_passwd): Simplify tests to actually read the file.
Set state to loaded before making internal_getpwXX calls.
Replace search_for calls by equivalent internal_pwgetXX calls.
(internal_getpwsid): Use passwd_state.isuninitialized to decide
to call read_etc_passwd.

two of the four arguments. Set gid to myself->gid and username
to cygheap->user.name ().
(getgroups32): Simply call internal_getgroup.
(getgroups): Call internal_getgroup instead of getgroups32.
(setgroups32): Call internal versions of get{pw,gr}XX.
