* cygheap.h (cygheap_user::issetuid): New method.
* dtable.cc (dtable::vfork_child_dup): Use new method to determine if we are in "setuid mode." * fork.cc (fork_parent): Ditto. * spawn.cc (spawn_guts): Ditto. * 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. (build_env): Don't add retrieved value to dstp if it is 'dont_add'.
