  31 dnl $Log: configure.in,v $
  32 dnl Revision 1.13  2000/06/17 13:51:03  mdw
  33 dnl Whoops.  Too eager with the mLib version.
  34 dnl
  35 dnl Revision 1.12  2000/06/17 12:57:47  mdw
  36 dnl New free counter noise generator, for use if /dev/random is
  37 dnl unavailable.
  38 dnl
  39 dnl Revision 1.11  2000/06/17 10:51:23  mdw
  40 dnl Version number changes.  Find maths library for Maurer's test.
  41 dnl
  42 dnl Revision 1.10  1999/12/22 16:03:31  mdw
  43 dnl New mLib version.  Find socket functions for pixie.
  44 dnl
  45 dnl Revision 1.7  1999/11/13 01:55:48  mdw
  46 dnl Don't be pedantic, because using `long long' as a multiprecision type
  47 dnl gets complained about.
  48 dnl
  49 dnl Revision 1.6  1999/11/11 18:56:14  mdw
  50 dnl Use `libtool' to generate a shared library.

  57 dnl
  58 dnl Revision 1.3  1999/10/24 10:20:36  mdw
