   3 # The ACK ANSI C compiler has an nice trick to reduce the size of programs
   4 # that do not use floating point.  If a program uses floating point then the
   5 # compiler generates an external reference to the label '_fp_hook'.  This makes
   6 # the loader bring in the floating point printing and conversion routines
   7 # '_f_print' and 'strtod' from the library libd.a.  Otherwise two dummy
   8 # routines are found in libc.a.  (The printf and scanf need floating point
   9 # for the %f formats, whether you use them or not.)
