Early changes commited for new branch Revision2.
Editorial and revision of bcd_set_long to include overflow check.
Changes reflect use of instance pointer to reference data variables
and detailed changes made to handling of carry out and leading
zeros when using 10's comp addition.
bcd_divide_v2 is now the the prefered division function - some minor
changes in the way leading zeros are removed from intermediate results.
Bcd_lib.c has the functions necessary for the bcd function library.
Modified bcd_divide_v2 to avoid side effects when input and output
variables point to the same location.
Editorial
Revised Makefile
Non-working version of bcd_set_random
Editorial changes in bcd_testing.c
Continued debug
Working on Inspiron. Testing the bcd_set_random function.
Revised the bcd_ostr function to only print digits above length up
to DIGITS limit. This avoids spurious output from  bcd_ostr.
Editorial bcd_lib
Revised file layout. Source files not in immediate use held in ./sources.
Added MAKEFLAGS=-B to Makefile
Added -m32 flag for the compiler. Is this a good idea?
More testing of bcd_set_random. Moved function to bcd_lib.
Modified makefile to do 32 and 64 bit builds. Minor change in bcd_set_str to allow for this.
