Sure. cc should also have the POSIX -D / -U semantics (see <https://pubs.opengroup.org/onlinepubs/7908799/xcu/cc.html>). As I said in bug 40960 I think a GCC configure option to install all those programs (as driver variants using slightly different specs, I suppose - but if you do that, you need to consider what happens if someone installs the output of -dumpspecs where the driver looks for specs, as a default set of specs there probably shouldn't override the special way those variants work) would make sense. Driver variants are likely to work more reliably than wrappers simply because they know exactly which options take separate arguments and so can't confuse option arguments with options themselves. -- Joseph S.
