SYS_PATH_ENV_VAR_NAME is "SystemRoot" so that will set win_sys_path to
%SystemRoot% (aka "C:\\windows" for most people).

However, if the user specifies --win-sys some_cruft, win_sys_path will
get set to that "some_cruft" (in options.c). User is the king.
Having said that --the man-page description of win-sys is confusing
and its value is set as win_sys_path without any sanity checks. If
win_sys_path is not a single base directory name, many other things
will break; for example in route.c we construct the command line for
route.exe as
argv_printf (&argv, "%s%sc ADD %s MASK %s %s",
get_win_sys_path(),
WIN_ROUTE_PATH_SUFFIX, <---- defined as "\\system32\route.exe"
network,
netmask,
gateway);
