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.
