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