I thought, last night, it would be useless that clang should behave
like cl.exe on mingw, even with "clang -target win32".

I suppose mingw users may specify individual include paths via command
line. The case "clang -target win32" can be considered as "cross
build".

But I rethink it might be useful as far as an user knows he is working
with ms headers.
For now, I leave _MSC_VER. In near future, I will reconfirm
"clang.exe" can behave similar among
{i686|x86_64}-{mingw32|mingw-w64|msvc}. Then I could prune _MSC_VER.

The conditioned block should be compiled also on mingw, that should make sense.
