You have the option to add SysNative to your system or user PATH under Windows, 
although that would best be done in your login script.

Cygwin starts with Cygwin paths /usr/bin:/bin and everything else is up to you.
You may add to your Cygwin PATH in your shell profile with code that switches 
depending on the existence of SysWOW64 and SysNative: cygpath -F 37 gives your 
application sysdir path, and cygpath -F 41 gives your x86 sysdir if there is one:

	https://docs.microsoft.com/en-ca/windows/win32/shell/knownfolderid

and please note that SysNative appears nowhere!
