This is the full script to compile it under MSYS2 CLANG.

#!/bin/bash
pacman -Suy mingw-w64-clang-x86_64-toolchain mingw-w64-clang-x86_64-cmake mingw-w64-clang-x86_64-openblas
git clone --recurse-submodules https://github.com/ggerganov/llama.cpp
cd llama.cpp
export CC=/clang64/bin/clang.exe
export CPP=/clang64/bin/clang++.exe
export LDFLAGS='-DLLAMA_NATIVE=ON -DLLAMA_BUILD_SERVER=ON -DBUILD_SHARED_LIBS=ON'
cmake .
make -j $(nproc)

If the issue is solved you should close it. Thank you for sharing the solution.

Or also:
in msys2/mingw

export CC=gcc
export CPP=g++
export LDFLAGS='-DLLAMA_NATIVE=ON -DLLAMA_BUILD_SERVER=ON -DBUILD_SHARED_LIBS=ON -DLLMODEL_CUDA=OFF'
git reset --hard
git clean -fd
git pull
cmake .
make
