From 3b91ea314d5b96f48955430b09d5bb072f7c1ef1 Mon Sep 17 00:00:00 2001
From: Adrian Thurston <thurston@complang.org>
Date: Fri, 27 Nov 2015 18:49:42 -0500
Subject: added an option, -b, for specifying the name of the program object

This also triggers the omission of C adapter funcs, which need to be present
only once in a binary that includes a colm code.
