Always include all the sources as we cannot include object libraries to be
subsumed. This allows us to conditionally build the swift runtime for foreign
hosts simultaneously (e.g. cross compile for Linux and Windows simultaneously).
`WIN32_LEAN_AND_MEAN` prevents "rarely-used" headers from being pulled in. This
significantly reduced preprocessor pressure, speeding up compile. It also
reduces the amount of cruft pulled in by the Windows.h.
`NOMINMAX` ensures that the `min` and `max` macros are not defined. These
macros collide with the use of `min` and `max` from C++ in certain cases: e.g.
`std::limits<T>`.
This patch is for libswiftCore.lib, linking with the library set of Visual Studio 2015. Clang with the option -fms-extension is used to build this port.
This is the approved subpatch of a large patch.
In PE-COFF formatted file, the offset of NT header can be greater than 0xFF. MS library defines it as LONG (32bit signed integer) in struct _IMAGE_DOS_HEADER.
