  29  * All volumes will have a volume header file with the filename
  30  * in one of these two formats. The difference is largely historical.
  31  * Early versions of System V Unix had severe limitations on maximum
  32  * filename length, and the '.vol' extension had to be shortened to
  33  * allow for the maximum volume name to fit. Those restrictions no
  34  * longer apply, but the descendants of those legacy AIX and HPUX
  35  * servers still use the shorter name.
  36  *
  37  * If you change VHDREXT, you must change VFORMAT as well. Don't try
  38  * this with token pasting in cpp; it's just too inconsistent in
  39  * across C compilers.
  40  *
  41  * Note that <afs/param.h> must have been included before we get here.
