All three patches look fine to me, and functionality-wise are a strict
improvement over the status quo. But I suspect in the long run we'd need
to keep all of the Apple bits in their own case-arm, like:
# this must come first, so we prefer it over "* clang".
"Apple LLVM" | "Apple clang")
print_apple_magic
;;
clang | *" clang")
print_flags clang
;;
and then apple_magic does the version conversion from Wikipedia I linked
to earlier.
I don't think your patch is really making it significantly harder to get
there, though splitting up "Apple LLVM" and "Apple clang" feels a bit
like it's the wrong direction.
I wasn't personally planning to take that next step, as I lack the
platform to test it on. And as noted, unless you have a pretty old
version of Xcode, it doesn't matter either way (so I'm content to leave
it until dev with a mac is bitten by it and cares enough to make it more
accurate).
