# Remove attempts by configure to specify a -isysroot path on Lion.
# It's never needed on Lion because the correct default is set within
# the compiler and because a CLT only user will never have an SDK path.
# This stops a compile error for CLT-4.3 where configure malforms the
# conftest command by using -isysroot without a path argument. This
# is what the command looks like when it's missing the arg:
# -isysroot -mmacosx-version-min=10.7
