Here is what the source code says:

raster/r.in.gdal/main.c
/*
 * r.in.gdal imports many GIS/image formats into GRASS utilizing the GDAL
 * library
 *
 * copyright of this file
 * Author: Frank Warmerdam
 *
 * Added optional GCP transformation: Markus Neteler 10/2001
 * TODO: most unreferenced formats are read in with negative coordinates - desired??
 */

See the last line... open for discussion.
