This fixes a build failure with meson 1.3.0, which was caused by a bugfix in Meson that made the cc.compile() check succeed on MSYS2 MinGW and enable DirectXMath SIMD, which in turn triggered the broken `__cpuid()` issue mentioned in the meson.build file.

Subject: [PATCH] Inc: Use two-argument cpuid when using recent MinGW
|
|
|
|
Since 2021, when building with MinGW if `intrin.h` is included
|
|
(directly or indirectly), it will redefine `__cpuid` to use the
|
|
intrinsic version of it, instead of the macro defined by GCC's
|
|
`cpuid.h`. Detect this case, and use the two-argument prototype
|
|
instead.
