The following compilers are known not to compile OpenTTD:
In general, this is because these old versions do not (fully) support modern
C++11 language features.
- Microsoft Visual C++ (MSVC) 2013 and earlier.
These old versions do not support modern C++ language features.
- GNU Compiler Collection (GCC) 3.2 and earlier.
These old versions fail due to OpenTTD's template usage.
- GNU Compiler Collection (GCC) 4.5. It optimizes enums too aggressively.
See https://github.com/OpenTTD/OpenTTD/issues/5513 and references therein.

If any of these compilers can compile OpenTTD again, please let us know.
Patches to support more compilers are welcome.
- GNU Compiler Collection (GCC) 4.7 and earlier.
- Clang/LLVM 3.8 and earlier.
