#ifdef CHECK_FUNCTION_EXISTS
Fix CheckFunctionExistsEx() cmake macro on win32 For example under mingw64 it could not detect that strtok_r() exists, because it checks with: void *p = func_name; And for this you need the function to be defined, so just sync our CheckFunctionExistsEx.c with CheckFunctionExists.c from cmake (and later we should drop them out) since it does correct things to detech functions existence. Also for WIN32 there is -FIwinsock2.h -FIws2tcpip.h, and I guess that is not works for mingw gcc (since -F in gcc is framework, and in windows -FI is like -include in gcc). But looks like we do not need them already (due to fixed CheckFunctionExistsEx()). Refs: #605
