__MSVCRT__ vs _WIN32

[wrotycz]

I noticed that for windows specific stuff check for __MSVCRT__ is used.

Most other >>projects<< use test for _WIN32.

What is the rationale for that?

--

#if defined __MSVCRT__

    #include <fcntl.h>

    #include <io.h>

#endif

#if defined(__MSVCRT__)

    setmode(STDIN_FILENO, O_BINARY);

    setmode(STDOUT_FILENO, O_BINARY);

#endif

Also, according to MSDN

_WIN32 Defined as 1 when the compilation target is 32-bit ARM, 64-bit ARM, x86, or x64. Otherwise, undefined.
