V0.8: Remove deprecated #ident and fix some other compile warnings
...
This patch removes #ident since it is deprecated in recent gcc
versions. It also removes all the CVS comments and fixes a few
other compilation warnings. There are still a few compilation
warnings, but this takes care of most of them. Fixing the rest
will require a bit more thought.

V0.8: do signed comparisons and fix verinum < and <=
...
This patch fixes the verinum < and <= operators to directly
compare the long result not the difference. Because of overflow
the difference can give an incorrect value. Using a long value
is technically wrong, but that will need to be a different
patch. It also fixes the eval_leeq_() routine to correctly build
the largest value in a signed comparison.
