David,

Yikes!  You are quite right.  I have corrected this in CVS.  I normally
hate to change stable C APIs, even when they are wrong, but I will break
my rule of thumb in this case because:

  1) This function is very very rarely used.

  2) The change doesn't affect the ABI.  At most it would mean calling
     code needs to be altered a bit to compile.

Best regards,
