misspelled test flag in configure
in configure: 25284: CPPFLAGS="$CPPFLAGS -fno-for-scoping" should be CPPFLAGS="$CPPFLAGS -fno-for-scope"
this flag is unsupported on osx maverics with clang, however the test does not detect this b/c of the misspelling.
This is also the cause for an initial workaround mentioned as part of issue
#45 (but not the core issue there)
