Doesn't that break Windows CE?
Ooh, we have a reviewer that actually pays attention!
_M_ARM indicates the arm instruction set version targeted, so we only do this
for armv7 or newer. The old VC compilers for Windows CE target armv4, so they
have _M_ARM == 4.
We could also check _M_ARMT which indicates whether we're building for thumb.
That'd probably be even more correct here I guess.
If you ever cared about that...
In theory at least - we still have a mingw32ce fate instance, but I haven't
tried running such code on an actual device for many years.
The latest MSVC version (at least the normal, public ones I've seen) that had
ARM compilers for CE was 2008, and that one defaulted to armv4, until they
went absent and returned with windows phone 8, for armv7.
Also, just for reference, libav doesn't build with the official CE (or
windows mobile) SDKs - it's missing way too much stuff, that mingw32ce
fills in. (And even then, the mingw32ce headers need to be patched for
libav to be buildable.)
