be kept as clean as possible.

Support for swapping real and effective user and group IDs is incomplete.
On WinNT Cygwin provides \f(CW\*(C`setuid()\*(C'\fR, \f(CW\*(C`seteuid()\*(C'\fR, \f(CW\*(C`setgid()\*(C'\fR and \f(CW\*(C`setegid()\*(C'\fR.
However, additional Cygwin calls for manipulating WinNT access tokens
and security contexts are required.
