Thanks for the bug report. In config.h try commenting out the line 

#define HAVE_LOG1P 1

and running make clean; make

I believe the configure script is finding a log1p() in the system math
library but the prototype is not included due to the ansi compiler
option.  This is a problem with the current configure script.
