Wrong BOOST_PFR_CORE_NAME_PARSING with "clang for MSVC"

[bansan85]

Under Windows with Visual Studio Installer, install "clang compiler for Windows"

With CMake, generate a project with toolset "ClangCL" : -G"Visual Studio 2022" -T ClangCL.

Build.

In this case, _MSC_VER is defined but I need to use the BOOST_PFR_CORE_NAME_PARSING from __clang__.

Solution is to check __clang__ first :

#ifndef BOOST_PFR_CORE_NAME_PARSING
#   if defined(__clang__)
#       define BOOST_PFR_CORE_NAME_PARSING (sizeof("auto boost::pfr::detail::name_of_field_impl() [MsvcWorkaround = ") - 1, sizeof("}]") - 1, backward("."))
#   elif defined(_MSC_VER)
#       define BOOST_PFR_CORE_NAME_PARSING (sizeof("auto __cdecl boost::pfr::detail::name_of_field_impl<") - 1, sizeof(">(void) noexcept") - 1, backward("->"))
#   elif defined(__GNUC__)
#       define BOOST_PFR_CORE_NAME_PARSING (sizeof("consteval auto boost::pfr::detail::name_of_field_impl() [with MsvcWorkaround = ") - 1, sizeof(")]") - 1, backward("::"))
#   else
// Default parser for other platforms... Just skip nothing!
#       define BOOST_PFR_CORE_NAME_PARSING (0, 0, "")
#   endif
#endif

Close since fix works. Thanks.
