* fixed-obj.mk: New file to support fine-grain fixed-point functions. * Makefile.in (fixed_point): Define. Check if fixed_point is yes to build support functions. * configure.ac: Check for fixed_point support. * configure: Regenerated. * gen-fixed.sh: New file to generate lists of fixed-point labels, funcs, modes, from, to.
