  there is two __ and that's usually a convention when remapping a
public library (libc in that case) symbol to an internal one or a 
macro in the system includes. 
  The signbit() call is from trio the compatibility library (apparently
the libc is missing some of the "advanced" function libxml2 needs or
well that configure think it is needed). In this case signbit is for
floating point portability for XPath.
