Yes, you're right. This should fix it:
2009-04-30 Bruno Haible <br...@clisp.org>
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.
