    1.25 +// constructor template of base_from_member.  Constructor templates will be
    1.26 +// generated from one argument to this maximum.  Code from other files can read
    1.27 +// this number if they need to always match the exact maximum base_from_member
    1.28 +// uses.  The maximum constructor length can be changed by overriding the
    1.29 +// #defined constant.  Make sure to apply the override, if any, for all source
    1.30 +// files during project compiling for consistency.
