Should be in a different patch since it effects the whole project.

DmitryK already mentioned it previously; you only need to disabled MinGW64 since clang isn't seeing those errors.

Disable avx512 when on mingw cross build, as .seh_savexmm
build error reports if avx512 is enabled.

Rather than changing this whole block to indent it further following the
new condition check, I think a simpler fix might be to insert:

if is_windows and cc.get_id() != 'clang'
	i40e_avx512_cc_support = false
endif

just after the initial assignment to i40e_avx512_cc_support. [Alternatively,
you can include those conditions in the assignment itself, but it's
probably more readable done separately as I show above.]

Agree, seems clear to put the logic block separately. Thanks~

Dmitry found a lighter alternative option to be tested and discussed.

Is this issue being looked at?

Seems the issue still exist on the platform which CPU has AVX512 capability, I think previous patch is not verified to cover this case.
Will send hotfix patch for this.
