compiler-rt builtins currently doesn't build on MSVC 2019,
I the problem is that compiler-rt\lib\builtins\int_math.h includes the header ymath.h.
according to eg. https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/finite-finitef?view=vs-2019 the header to include is float.h
also the ymath.h file contains the comment /* ymath.h internal header */ so probably shall not be used.

I do not know how compiler-rt works only tried to compile rustc that is using compiler-rt
How shall I go forward with this problem?
