Executables compiled on Windows will not work on Linux, the source has to be
recompiled for this. About your problem, it's a bit tricky, because _fmode()
is a function on some platforms and a variable on others. The best way to
handle this would be to use a wrapper function and conditional compilation
(#ifdef etc.).
