// Cross-platform C solution test suite.
// $CC is supplied by CI matrix (gcc / clang / msvc).

// Run locally:
//   CC=gcc   judge sum.jdg .
//   CC=clang judge sum.jdg .
//
// On Windows, build_windows branches on CC because MSVC's cl has a
// different CLI from clang. Executed via `cmd /C`, so %VAR% is cmd syntax.
