+       Fix bug introduced on 2009-04-25.
+       * lib/math.in.h (gl_signbitf_OPTIMIZED_MACRO,
+       gl_signbitd_OPTIMIZED_MACRO, gl_signbitl_OPTIMIZED_MACRO): New macros.
+       * lib/signbitf.c (gl_signbitd): Undefine if gl_signbitf_OPTIMIZED_MACRO
+       is defined.
+       * lib/signbitd.c (gl_signbitd): Undefine if gl_signbitd_OPTIMIZED_MACRO
+       is defined.
+       * lib/signbitl.c (gl_signbitd): Undefine if gl_signbitl_OPTIMIZED_MACRO
+       is defined.
+       Reported by Elbert_Pol <elbert.pol@gmail.com>.
