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. learn.microsoft.com
