* syscalls.cc (seteuid32): Ditto.
(setegid32): Ditto.
* environ.cc (spenv::retrieve): (Suggested by Pierre Humblet) Do potential
recalculation of cygheap_user stuff when in setuid mode. Return special value
when environment variable exists but should not be added.

(conv_envvars): Use NL macro to fill in name and namelen.

user == SYSTEM.

* environ.cc (build_env): Add debugging statement.
(spenvs): Switch functions for USERDOMAIN and USERNAME.
* spawn.cc (spawn_guts): Move environment initialization prior to
cygheap_setup_for_child or environment info will never be copied to child.

* cygheap.h (cygheap_user::set_logsrv): Remove declaration.
(cygheap_user::set_domain): Ditto.
(cygheap_user::env_domain): Declare new method.

Use env_logsrv to get logon server.
(cygheap_user::env_logsrv): Calculate server name here rather than relying on
it having been previously calculated.
(cygheap_user::env_domain): Ditto for domain name.
(cygheap-user::env_name): New method.
* syscalls.cc (seteuid32): Do not get or set the environment. Do not call
LookupAccountSid nor internal_getlogin. Set cygheap->user name and sid from
the passwd entry.
* uinfo.cc (uinfo_init): Only call internal_getlogin when starting from a non
Cygwin process and use the values returned in user.
(internal_getlogin): Simplify to case where starting from a non Cygwin process.
Store return values in user and return void. Do not set the Windows default
environment.
* dcrt0.cc (dll_crt0_1): Call uinfo_init only when needed. Do not set
myself->uid nor reset user.sid.
* spawn.cc (spawn_guts): Get the sid from cygheap->user. Always
RevertToSelf(). Don't set uid in impersonated case.
* cygheap.cc (cygheap_user::set_sid): Do not set orig_sig.
(cygheap_user::set_orig_sid): New.
* cygheap.h: Declare cygheap_user::set_sid.
* winsup.h: Add argument to uinfo_init().
in the license.
* README: Renamed.
* README.w32api: Renamed from README. Modified license to remove
the restriction of notifying the author based on the fact that the
author is unreachable at the notified address.
* Makefile.in (VERSION): Change to 2.0.
(GetPW): Add parameter to (dis)allow printing of Windows username.
Use defines instead of numerical constants where possible.
Try avoiding impersonation problem. Rearrange to print Windows
username only if it's different from Cygwin username.
(ChangePW): Use defines instead of numerical constants where possible.
(main): Call GetPW with additional parameter. Change error text.
* passwd.c (GetPW): Handle case of user-edited /etc/passwd
with cygwin_internal (CW_EXTRACT_DOMAIN_AND_USER, ...).
* libm/math/e_pow.c (__ieee754_pow): Fix case whereby
x is close to -1.0 and y is very large to use ax (absolute value)
instead of x.
* libm/math/ef_pow.c (__ieee754_powf): Ditto.
homepath to NULL.
(cygheap_user::set_logsrv): Fix free'ing of plogsrv.
* cygheap.h (cygheap_user::cygheap_user): Initialize homedrive and
homepath to NULL.
user name change.
(cygheap_user::set_logsrv): Allocate enough space for leading \\ so that we can
put this in the environment, if needed.
* cygheap.h (homebodies): New enum.
(cygheap_user::homedrive): New field.
(cygheap_user::homepath): Ditto.
(cygheap_user::env_logsrv): New method.

(spenv): New class.
(spenvs): New array, renamed from forced_winenv_vars, using spenv.
(spenv::retrieve): New method.
(build_env): Rename from 'winenv' -- one stop shopping for building new
environment blocks for both windows and "unix".
* environ.h (build_env: Declare.
(winenv): Delete declaration.
(envsize): Ditto.
* spawn.cc (spawn_guts): Use build_env to build windows and cygwin environment
blocks.
* uinfo.cc (internal_getlogin): Eliminate environment manipulation. Default to
info from GetUserName if it exists. Move HOMEPATH and HOMEDRIVE stuff
elsewhere. Move HOME setting elsewhere. Only set HOME environment variable in
processes that are not parented by a cygwin process.
