As Larry wrote, this has nothing to do with Cygwin:
64 bit apps on 64 bit find their stuff as usual in C:\Windows\System32.
For 32 bit apps on 64 bit Windows, all access to C:\Windows\System32
is redirected to the directory C:\Windows\SysWOW64, which is populated.
with the 32 bit WIndows tools and DLLs.
Since Vista you can also access the 64 bit C:\Windows\System32 from 32
bit apps, by using the fake path C:\Windows\Sysnative
HTH,
Corinna
