  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=46114

  Log:
    configure.in: do not disable ucontext.h
    
    * configure.in (ac_cv_func_{getcontext,setcontext}): do not
      disable ucontext.h entirely, but disable use of functions only.
      `ucontext_t` is necessary in the signal handler now.
