--- Comment #4 from Daniel Macks <dmacks at netspace.org> ---
The boilerplate for this sort of autoconf check is something like:


saved_CXXFLAGS="$CXXFLAGS"
CXXFLAGS="-fno-check-new $CXXFLAGS"
AC_MSG_CHECKING([for -fno-check-new compiler flag])
AC_TRY_COMPILE([], [int main (void) { return 0; }],
  AC_MSG_RESULT([yes]),
  AC_MSG_RESULT([no])
  CXXFLAGS="$saved_CXXFLAGS"
])


Obviously could extract this result into a temp variable first and concat into
the larger CXXFLAGS assignments in the relevant case/esac sections rather than
having the test itself leave the result in the live variable.
