45 dnl New library configuration stuff from `common'.
47 dnl Revision 1.13 2000/06/17 13:51:03 mdw
48 dnl Whoops. Too eager with the mLib version.
50 dnl Revision 1.12 2000/06/17 12:57:47 mdw
51 dnl New free counter noise generator, for use if /dev/random is
54 dnl Revision 1.11 2000/06/17 10:51:23 mdw
55 dnl Version number changes. Find maths library for Maurer's test.
57 dnl Revision 1.10 1999/12/22 16:03:31 mdw
58 dnl New mLib version. Find socket functions for pixie.
60 dnl Revision 1.7 1999/11/13 01:55:48 mdw
61 dnl Don't be pedantic, because using `long long' as a multiprecision type
62 dnl gets complained about.
64 dnl Revision 1.6 1999/11/11 18:56:14 mdw
65 dnl Use `libtool' to generate a shared library.
