  Convert hours, minutes, seconds to days.
  
  This function is part of the International Astronomical Union's
  SOFA (Standards of Fundamental Astronomy) software collection.
  
  Status:  support function.
  
  Given:
  s         char    sign:  '-' = negative, otherwise positive
  ihour     int     hours
  imin      int     minutes
  sec       double  seconds
  
  Returned:
  days      double  interval in days
  
  Returned (function value):
  int     status:  0 = OK
  1 = ihour outside range 0-23
  2 = imin outside range 0-59
  3 = sec outside range 0-59.999...
  
  Notes:
  
  1)  The result is computed even if any of the range checks fail.
  
  2)  Negative ihour, imin and/or sec produce a warning status, but
  the absolute value is used in the conversion.
  
  3)  If there are multiple errors, the status value reflects only the
  first, the smallest taking precedence.
