30 dnl
31 dnl $Log: configure.in,v $
32 dnl Revision 1.17 2000/07/03 18:14:53 mdw
33 dnl Version bump.
34 dnl
35 dnl Revision 1.13 2000/06/17 13:51:03 mdw
36 dnl Whoops. Too eager with the mLib version.
37 dnl
38 dnl Revision 1.12 2000/06/17 12:57:47 mdw
39 dnl New free counter noise generator, for use if /dev/random is
40 dnl unavailable.
41 dnl
42 dnl Revision 1.11 2000/06/17 10:51:23 mdw
43 dnl Version number changes. Find maths library for Maurer's test.
44 dnl
45 dnl Revision 1.10 1999/12/22 16:03:31 mdw
46 dnl New mLib version. Find socket functions for pixie.
47 dnl
48 dnl Revision 1.7 1999/11/13 01:55:48 mdw
49 dnl Don't be pedantic, because using `long long' as a multiprecision type
50 dnl gets complained about.
51 dnl
52 dnl Revision 1.6 1999/11/11 18:56:14 mdw
53 dnl Use `libtool' to generate a shared library.
54 dnl
55 dnl Revision 1.5 1999/11/11 17:47:34 mdw
56 dnl Updates for new configuration system, and `mptypes' generator.
57 dnl
58 dnl Revision 1.4 1999/11/11 00:58:19 mdw

60 dnl
61 dnl Revision 1.3 1999/10/24 10:20:36 mdw
62 dnl Modify for standalone distribution. The library's getting far too large
63 dnl to be sensibly embedded in other programs.
