  32 --  This package contains definitions for initial sizes and growth increments
  33 --  for the various dynamic arrays used for the main compiler data structures.
  34 --  The indicated initial size is allocated for the start of each file, and
  35 --  the increment factor is a percentage used to increase the table size when
  36 --  it needs expanding (e.g. a value of 100 = 100% increase = double)
  37
  38 --  Note: the initial values here are multiplied by Table_Factor as set by the
  39 --  -gnatTnn switch. This variable is defined in Opt, as is the default value
  40 --  for the table factor.
