This is OK. I don't think there's any reason to be too literal-minded about requiring review by a language front-end maintainer for something like this. Your patch clearly is not making the compiler (including C++) behave worse than before, and once we're blowing away the referent of the macro blowing away the macro itself is obvious. So, I think we should all feel free to consider trivial updates to language front-ends when making a language-independent change. Of course, people should use their judgment; if this policy starts getting abused, we'll have to go back to a stricter point of view. Thanks,

Of I'm doubtful about the triviality of the Ada parts of <http://gcc.gnu.org/ml/gcc-patches/2010-06/msg01968.html> (the Ada changes in the following two patches with such changes are smaller), especially as I'm saying that Ada should really be doing something else and the argv/argc reconstitution is intended as a temporary fix until the Ada maintainers can make the code work properly with logical decoded options.

It's certainly better to err on the side of caution. Thanks,
difficult to get at present without calling cc1 directly, as the driver will usually give a generic error itself; they should be easier to get once the driver is sharing the common option processing code. If you're concerned about text size increase from adding a pointer to the cl_option structure (of which there are about 900 constant instances in GCC, depending on the target), note that this patch series will end up replacing the flag_var pointer in that structure with an offset that should certainly fit in a "short". I think the int-sized elements other than "flags" should also fit in "short" (or in unsigned char in some cases), although I have no plans to work on such text size reductions. Bootstrapped with no regressions on x86_64-unknown-linux-gnu.
