-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 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
