commit 0c77e93a3f6abfd106c320be8324eb3fef4b0491
Author: Ken Raffenetti <raffenet at mcs.anl.gov>
Date:   Tue Feb 25 07:48:20 2014 -0600

    use AC_SEARCH_LIBS for additional libraries
    
    The functions searched generally live in libc, but some platforms (e.g.
    Solaris) have them in special libraries. Use AC_SEARCH_LIBS to include
    the extra libraries when needed. Fixes #2034
