FWIW, the Command Line Tools (which is significantly smaller than Xcode)
includes the headers (at
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/), and will
also set Clang’s default header search path so that these can be found. You can
get that with “xcode-select --install”, though if you’re trying to future-proof
your setup I’ve heard rumors that the Command Line Tools may be dropped as well
:( I don’t know what Homebrew finally decided on, but I do remember it being
“pretty broken” (well, more than it usually is) during the macOS Mojave beta
period because many of their formulas depended on /usr/include existing and
would only build if you installed the headers package.
