You can get a recent build of LLVM-MinGW from https://github.com/mstorsjo/llvm-mingw/releases. The main benefit with this compiler toolchain is that the released archives are self contained. There is NO installation necessary. Just ~516MB of disk space.

TCC is a very lightweight C compiler. Its main advantages are that it takes up very little storage space (~5MB), and compiles much more quickly than the other compilers listed here. However, it has several limitations. For these reasons, a different and more advanced compiler is recommended.
- It barely optimizes the resulting binaries, so resulting executables will be slower. That's partly why it compiles faster.
- It is not as stable as GCC or Visual Studio. While it compiles V and its standard library perfectly, you may encounter issues if working with C interop, or with external modules that depend on C libraries.
- It is not as stable as other supported compilers. While it compiles V and its standard library perfectly, you may encounter issues if working with C interop, or with external modules that depend on C libraries - Refer to [issues in this PR](https://github.com/vlang/v/pull/9030), for example.
Due to its small size, TCC is downloaded automatically if no existing C compiler is found. By default, TCC64 would be downloaded for 64-bit Windows users and TCC32 for 32-bit Windows users.
[Original TCC](https://repo.or.cz/tinycc.git) isn't fully compatible with V, and thus is cloned and patched in [this official tccbin repo](https://github.com/vlang/tccbin) to fully work with V. As a result, you should always use this patched TCC instead of original one.
For 64-bit Windows users, you can also install it manually by using `.\make.bat -tcc`(TCC64) / `.\make.bat -tcc32`(TCC32), or by running `git clone https://github.com/vlang/tccbin/tree/thirdparty-windows-amd64 thirdparty/tcc`(TCC64) / `git clone https://github.com/vlang/tccbin/tree/thirdparty-windows-i386 thirdparty/tcc`(TCC32) from V's root folder.
For 32-bit Windows users, you can also install it manually by using `.\make.bat -tcc`, `.\make.bat -tcc32`, or `git clone https://github.com/vlang/tccbin/tree/thirdparty-windows-i386 thirdparty/tcc` - Any of them would install TCC32 for you.
Due to its small size, TCC64 or TCC32 is downloaded automatically if no existing C compiler is found on 64-bit or 32-bit Windows, respectively. **For 64-bit Windows**, you can also install TCC64 or TCC32 manually by using `.\make.bat -tcc`(TCC64) / `.\make.bat -tcc32`(TCC32), or by running `git clone https://github.com/vlang/tccbin/tree/thirdparty-windows-amd64 thirdparty/tcc`(TCC64) / `git clone https://github.com/vlang/tccbin/tree/thirdparty-windows-i386 thirdparty/tcc`(TCC32) from V's root folder. **For 32-bit Windows**, you can also install TCC32 manually by using `.\make.bat -tcc`, `.\make.bat -tcc32`, or `git clone https://github.com/vlang/tccbin/tree/thirdparty-windows-i386 thirdparty/tcc`.
