New submission from Masayuki Yamamoto: Platform that appeared warning is Vista Cygwin x86. Interpreter execution doesn't crash because _setmode function is supplied from cygwin1.dll that always linked. Warning reason is header io.h [*] doesn't include to source file. Therefore I wrote two patches for 3.7 and 2.7.
