# You must have "$ARCH-unknown-redox-gcc" in your PATH, add it from Redox build system
# mkerrors: You need to patch "$CC" to "gcc" at the bottom of the script, also "$(uname)" to "Redox"
# mkerrors: You need to comment out "#include <netinet/ip6.h>" and "#include <sys/signal.h>" since Redox doesn't have it
