+## WARNING: THE ORIGINAL OF THIS SCRIPT IS IN:
+## https://github.com/vlang/v/blob/master/thirdparty/build_scripts/thirdparty-freebsd-amd64_tcc.sh ,
+## I.E. IN THE MAIN V REPOSITORY. IF YOU NEED TO MAKE CHANGES, CHANGE THAT.
+##
+## THE `build.sh` FILE IN `vlang/tccbin` REPO IS A COPY, RECORDED AT THE TIME
+## OF REBUILDING, FOR EASIER/RELIABLE REPRODUCTION OF HISTORIC VERSIONS.
+## IT IS NOT INTENDED TO BE MODIFIED.
