[MSVC] Boost\libs\container_hash failed to build

[QuellaZhang]

Issue description:
Boost\libs\container_hash failed to build due to warning C4996 on MSVC, regress by microsoft/STL#2759. Could you please take a look?

Build step:

1. git clone -c core.autocrlf=true --recursive ​https://github.com/boostorg/boost.git F:\gitP\boostorg\boost
2. open a VS2022 x86 command prompt and browse to F:\gitP\boostorg\boost
3. .\bootstrap
4. .\b2 headers variant=release --build-dir=out\x86rel address-model=32
5. .\b2 variant=release --build-dir=out\x86rel address-model=32
6. .\b2 -j16 variant=release --build-dir=..\out\x86rel libs\container_hash\test

Should be fixed now, but shouldn't you be getting the same error in hash_reference_values.cpp, which also uses std::complex<int>?

This should be fixed now as well.
