# brintc++ — the C++ compiler driver for wasm32-hwjs-linux.
#
# Same front-door shape as brintcc (read that header for the libc selection and
# why this execs), plus one thing: the C++ implementation compiles the C++ TUs
# itself and DELEGATES the link to the C driver, so the two must be the same
# libc arm. Naming that driver explicitly is deliberate — it used to be found
# by name, and a PATH surprise could swap the substrate underneath a link.

# readlink -f, not dirname alone: these front doors are meant to be symlinked
# into a prefix on PATH, and a symlink's dirname is the prefix, not this repo.
