** Convert degrees, arcminutes, arcseconds to radians.
**
** Given:
** s char sign: '-' = negative, otherwise positive
** ideg int degrees
** iamin int arcminutes
** asec double arcseconds
**
** Returned:
** rad double angle in radians
**
** Returned (function value):
** int status: 0 = OK
** 1 = ideg outside range 0-359
** 2 = iamin outside range 0-59
** 3 = asec outside range 0-59.999...
**
** Notes:
**
** 1) The result is computed even if any of the range checks fail.
**
** 2) Negative ideg, iamin and/or asec 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.
