You are assuming that this symbol is one that is predefined in Delphi.
That is not the case. The library probably comes with an include file
defining symbols, e.g. for different versions of the Delphi compiler it
may be compiled with. Such a file usually has the extension INC and is
included in the libraries units near the top through and {$I
filename.inc} statement. Such a file can define any symbol it wants
with the $DEFINE directive, which can of course also be used directly
inside a unit. In addition symbols can be defined for a project in the
project options dialog.
