List software that does not depends on C/C++

Conditions:
A.The software X must not require the presence of C/C++ compiler on the system(GCC/LLVM/MSVC/TCC/etc) to successfully compile a new version.
B. If its interpreted or JIT compiled, its interpreter/JIT compiler must follow condition A.
C. It may link to C libraries supplied by OS and environment by default, but should not have internal dependencies on them.

IIRC FreePascal has a compiler and a standard library that doesn't depend on libc. its compiler is self-hosting. therefore, anything written for it or in a compatible subset of Turbo Pascal, Object Pascal and (with Lazarus) Delphi will be C-independent.
