Browse Source 
(cygheap_user::set_domain): Ditto.
* cygheap.h (cygheap_user::set_logsrv): Remove declaration.
(cygheap_user::set_domain): Ditto.
(cygheap_user::env_domain): Declare new method.
(cygheap_user::env_name): Ditto.
* environ.cc (spenvs): Add two environment variables.
* spawn.cc (spawn_guts): Call build_env after RevertToSelf.  Always set
ciresrv.mount_h.
(cygheap_user::ontherange): Recalculate homedrive/homepath if they are empty.
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().
