I can't think of an example with GCC. It does things like
-fdisable-some-option, but I can't think of a multicharacter _flag_.
Also, I've always felt that the way Java VMs take arguments feels like it
grew organically into something terrible (-Xmx512m! -Xkill-the-rabbit!). I
can't speak to LLVM/Clang.

Could you post a few specific examples? It's hard to generalize with this
sort of thing.

(And don't even get me started on Windows. Should I be using /? or -? or =?
or -help or --FML-this-OS-doesn't-support-CLI)
