[Boost-users] Why is BOOST_OS_WINDOWS defined on Linux

3 May 2018

      Hello,

Everything is in the title, the following code compiles and shows
"Windows" even though I'm running Fedora 28. I can't understand.

    #include <iostream>

    #include 

    int main()
    {
    #if defined(BOOST_OS_WINDOWS)
        puts("Windows");
    #endif
    }

I'm using Boost 1.66 with GCC 8.0.1.

Regards,
