Nothing. Just use always the UNICODE API, rather than the ANSI API:
 #include <sys/cygwin.h>
 DWORD
 my_GetFileAttributes (const char *cygwin_multibyte_filename)
 {
 DWORD attr = INVALID_FILE_ATTRIBUTES;
 PWCHAR w32_filename = cygwin_create_path (CCP_POSIX_TO_WIN_W,
					 cygwin_multibyte_filename);
 if (w32_filename)
 {
	attr = GetFileAttributes (w32_filename);
	free (w32_filename);
 }
 return attr;
 }
