^A & ^B characters when trying to configure log4cpp

Question

When I am trying to configure the log4cpp which is cloned from the location Log4cpp CodeGit.

I observe the ^A & ^B characters at the end of the #ifdef macros, due to which compilation is not going through.

Steps I followed are
1) git clone git://git.code.sf.net/p/log4cpp/codegit log4cpp-codegit
2) ./autogen.sh
3) ./configure

Excerpt of Output file include/log4cpp/config.h

* Define to 1 if you have the <dlfcn.h> header file. */
#ifndef LOG4CPP_^A 
#define LOG4CPP_^A ^B 
#endif

/* Define to 1 if you have the `ftime' function. */
#ifndef LOG4CPP_^A 
#define LOG4CPP_^A ^B 
#endif

Please let me know if anyone face this issue and resolved.

Thanks.
