commit 32cec09d136060e02dfa28d65f2cb19028706652
Author: Andy Wingo <address@hidden>
Date:   Tue Apr 9 21:58:30 2013 +0200

    simplify configure checks for functionality provided by gnulib
    
    * configure.ac: Remove checks for pipe, stftime, times, and select, as
      our Gnulib modules already ensure they are provided.
    
    * libguile/stime.c: Rely on gnulib providing `times'.
