31 dnl $Log: configure.in,v $
32 dnl Revision 1.12 2000/06/17 12:57:47 mdw
33 dnl New free counter noise generator, for use if /dev/random is
36 dnl Revision 1.11 2000/06/17 10:51:23 mdw
37 dnl Version number changes. Find maths library for Maurer's test.
39 dnl Revision 1.10 1999/12/22 16:03:31 mdw
40 dnl New mLib version. Find socket functions for pixie.
42 dnl Revision 1.7 1999/11/13 01:55:48 mdw
43 dnl Don't be pedantic, because using `long long' as a multiprecision type
44 dnl gets complained about.
46 dnl Revision 1.6 1999/11/11 18:56:14 mdw
47 dnl Use `libtool' to generate a shared library.
49 dnl Revision 1.5 1999/11/11 17:47:34 mdw
50 dnl Updates for new configuration system, and `mptypes' generator.
52 dnl Revision 1.4 1999/11/11 00:58:19 mdw
53 dnl Use canned check for `ssize_t'.
55 dnl Revision 1.3 1999/10/24 10:20:36 mdw
56 dnl Modify for standalone distribution. The library's getting far too large
57 dnl to be sensibly embedded in other programs.
