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