Updated to use libtool 1.2 (with FreeBSD3.0 a.out v. elf detection).
Updated autoconf to 1.12 with sed patch (don't use stock 1.12).
aclocal.m4 is built using automake's aclocal, v1.3.
Updated mkdep to support libtool .lo files.
Updated automake provided macros for TERMIOS, STRTOD, MKTIME, PTRDIFF_T
Autoconf now checks to ensure C compiler supports ANSI C prototypes.
Updated make files templates.
-thread & -pthread are still treated as libraries, will need
additional work to use them as CFLAGS.
Eliminated HAVE_DCE define (was redundant) and its use. Code
now relies on draft4 and function existance tests.
