Agreed. gcc is bundling too much crap^Wstuff. libstdc++ should be separate,
much like the C library and other libs are.

But that's another storry! :-]

Hehe! I'm looking forward to seeing LLVM/CLanG being a proper replacement
for gcc, even on Linux-based systems! ;-)

Yes, sure. But it should:
 - happen in ./configure
 - use the new variable passing
 - hide the corresponding options from the menuconfig
 - have no impact on the code in scripts/build/cc/gcc.sh

Something along the lines of:

  printf "Checking if static link is possible..."
  case $(uname -s) in
    MacOS-X)	static_link_ok=""; printf "no\n";;
    *)          static_link_ok="y"; printf "yes\n";;
  esac
  add_to_kconfig_list static_link_ok

And to options that need it, add:
  depends on CONFIGURE_static_link_ok


Then, you could push a second patch:
 - don't check for static libs if static link is not available:
   - static libstdc++
   - static expat
so the user does not see spurious failed tests.

Yann E. MORIN.
