One assumption hidden behind the scripts of src/tools/msvc/ is that we
have never needed to support OpenSSL <= 1.0.1 these days (see for
example HAVE_X509_GET_SIGNATURE_NID always set to 1, introduced in
1.0.2) because the buildfarm has no need for it and there is no MSI
for this version for years (except if compiling from source, but
nobody would do that for an older version anyway with their right
mind). If you try, you would already get a compilation failure pretty
quickly. So I'd rather keep the code as-is and not add the extra
sudden-death check. Now that's only three extra lines, so..
