__USE_BSD is defined by default when compiling applications on Linux.
Cygwin/newlib does not have the complex system of defines which differ
between BSD/SYSV/POSIX/GNU/C89/C99/etc and allow to include and exclude
symbols based on that. The newlib system is much less elaborate. We
simply lack the volunteering manpower Linux and glibc have.
