All I say is, why setting a precedent at this point in the code,
when other places in the code are using cygwin_internal (or, fwiw,
cygwin_conv_to_posix_path, cygwin_conv_to_full_posix_path,
cygwin_conv_to_win32_path) without #ifdef/#endif bracket anyway.

There's also a pretty clear comment at the start of the file:

  /* We assume we're being built with and will be used for cygwin.  */
