Okay; I think that r33435 should fix it:

--- raster/r.external/main.c	(revision 33434)
+++ raster/r.external/main.c	(working copy)
@@ -454,12 +454,14 @@
 	struct Range range;
 	range.min = (CELL)info->range[0];
 	range.max = (CELL)info->range[1];
+	range.first_time = 0;
 	G_write_range(output, &range);
     }
     else {
 	struct FPRange fprange;
 	fprange.min = info->range[0];
 	fprange.max = info->range[1];
+	fprange.first_time = 0;
 	G_write_fp_range(output, &fprange);
 	write_fp_format(output, info);
 	write_fp_quant(output);

I'm assuming that the inaccuracy in the range is due to the lack of
the -r flag. Without that flag, GDAL calculates an approximate range
from a sampling of cells, rather than processing the entire map.
