Work around -Werror,-Wunused-macros with clang-cl
clang-cl as-is does not provide the intrinsics provided by MSVC; you need to
explicitly include Intrin.h (provided by clang) for that. So, as a hack,
specify CC/CXX as
clang-cl.exe -FIIntrin.h ...
to have the intrinsics always available. But Intrin.h includes stdlib.h, so by
the time sal/osl/w32/random.c defines _CRT_RAND_S before including stdlib.h, the
latter has already been included without _CRT_RAND_S support. So, as a second
hack, specify CC rather as
clang-cl.exe -D_CRT_RAND_S= -FIIntrin.h ...
But then clang-cl starts to emit -Werror,-Wunused-macros, as defining
_CRT_RAND_S in the main file has no effect here.
