Grumble.  Looks like testawk was never updated to print out label_color.  Must
have been one of those variables that got added late in the game.

Look at testawk.c down around line 227 --- add a printf to output label_color.
Then try again.

Now why every line  has pattern=-1073742784 is a mystery, but it's probably
because you don't initialize it in your BEGIN_RECORD block, and testawk 
doesn't initialize it either.  This is a flaw in testawk.  Unlike testawk,
though, draw_shapefile_map in xastir explicitly initializes all dbfawk 
variables to something sane, so that's not the problem.

Are the display level, font size, and label level you set in your dbfawk file
the same as the ones that testawk shows?
