-<p>By default, configure will detect SFU as a flavour of NetBSD, so we need to tell it that we want a Windows build target. We have to add -NOLOGO to the flags because some of the configure tests don't expect compiler output, but the version test does. If you are using a recent SDK then you need the -NODEFAULTLIB:atlthunk to work around the #pragma in atlbase.h but older SDKs (such as the one provided with the full version of VC7.1) do not have this problem.
