+ 
+       Second steps fixing +inform, +nancy, for MPFR.
+ 
+       * builtin.c (format_nan_inf): Use mpfr_signbit instead of mpfr_sgn.
+       * mpfr.c (force_mpnum): Check for NaN and leading minus and if so
+       set the signbit with mpfr_setsign.
+       (mpg_force_number): Copy in code from f_force_number to check
+       properly for +inf, +nan.

+ 
+       First steps fixing +inform, +nancy. Sigh.
+ 
+       * awk.h (is_ieee_magic_val): Add declaration.
+       * node.c (is_ieee_magic_val): Make extern, not static.
+       (r_force_number): Make the check smarter, catch -nan.
+

 +      Make gawk numeric comparisons act like C doubles.
 +      MPFR differs from doubles w.r.t. NaN, not sure why yet.
 +
 +      * awk.h (scalar_cmp_t): New enum.
 +      * builtin.c (format_nan_inf): Use mpfr_signbit, not mpfr_sgn.
 +      * eval.c (cmp_doubles): New routine.
 +      (cmp_scalars): Change type to bool, rework logic.
 +      * interpret.h (r_interpret): Rework scalar comparisons.
 +      * mpfr.c (mpg_cmp_as_numbers): New routine.
 +      * node.c: Use <math.h>, not "math.h", minor comment edits.
 +
 +2020-11-02         Arnold D. Robbins     <arnold@skeeve.com>
 +
        * re.c (make_regexp): Cast len parameter to int to avoid
        compiler warnings.
