Jerry DeLisle 2bb6de3a7e re PR libfortran/32611 (Print sign of negative zero) 
2007-07-15  Jerry DeLisle  <jvdelisle@gcc.gnu.org>
	    Francois-Xavier Coudert  <fxcoudert@gcc.gnu.org>

	PR fortran/32611
	* runtime/compile_options.c (set_std): Remove.
	(set_options): New function.
	(init_compile_options): Add initialization for -fsign-zero option.
	* gfortran.map (GFORTRAN_1.0): Rename _gfortran_set_std into
	_gfortran_set_options.
	* libgfortran.h (compile_options_t): Add sign_zero field.
	* io/write.c (output_float): Use the sign bit of the value to determine
	if a negative sign should be emitted for zero values.  Do not emit the
	negative sign for zero if -fno-sign-zero was set during compile.
