Is the clang bit only valid for Apple, or can we have it as a general section?

Apple only, normal clang explodes.

COVERAGE and GPROF flags don't apply either I assume?

Edit: COVERAGE does, GPROF does not.

gprof for sure not.

Checked the documentation. The Coverage flags are fine, but -pg does not exist.

um, they are not in the man pages

https://clang.llvm.org/docs/ClangCommandLineReference.html#cmdoption-clang-fprofile-arcs

Assuming this is the correct documentation?

ok, it does work, but the fortran part explodes with it enabled so I can't test it. -pg explodes.

AppleClang != Clang. They forked it a long time ago and have done terrible dark things to it since.

Ah, I see. In that case.

Could you please just delete the flags that do not apply? Commented out code that doesn't work anyway is just clutter ...
