* win32/win32.c (winnt_stat): support symbolic link and others. * win32/win32.c (w32_stati128, wstati128, name_for_stat, rb_w32_{,ul}stati128, wutimensat): follow above change. [Feature #14169] From: Takehiro Kubo kubo@jiubao.org git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61180 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
