With the Microsoft compiler (Microsoft (R) C/C++ Optimizing Compiler Version 19.28.29914 for x64) we get the warning like:

warning C4191 'operator': unsafe conversion from 'type_of_expression' to 'type_required'

for:

filesystem/include/ghc/filesystem.hpp

Line 1959 in cd6805e

static CreateSymbolicLinkW_fp api_call = reinterpret_cast<CreateSymbolicLinkW_fp>(GetProcAddress(GetModuleHandleW(L"kernel32.dll"), "CreateSymbolicLinkW"));

and
