mv utils.c reid.c In the original GSM 06.06 code drop, reid.c resides in the "utilities" collection (Dir_UTIL.zip), but there is also a copy of reid.c named utils.c in the "C" collection (Dir_C.zip), even though it is never compiled or linked as such. When I originally created the present Hg repository, I did not intend to include REID, only the main body of the codec - but I overlooked that utils.c copy, so it got imported. In the present time, however, it has become useful to have REID code in Hg for easier public study and discussion - so let's have it under its proper name.
