NO!!!  You have completely missed the point. The compiler is a
separate issue from the compilation environment, the libraries,
and the run-time environment.  The MS compiler will always
define _WIN32 and _MSC_VER even when used in an environment
which has unistd.h, htons, int64_t, etc.

Use the mechanism provided by configure, e.g. for unistd,h
use the HAVE_UNISTD_H macro.
