 # The PREDEFINED tag can be used to specify one or more macro names that are
 # defined before the preprocessor is started (similar to the -D option of e.g.
 # gcc). The argument of the tag is a list of macros of the form: name or
 # name=definition (no spaces). If the definition and the "=" are omitted, "=1"
 # is assumed. To prevent a macro definition from being undefined via #undef or
 # recursively expanded use the := operator instead of the = operator.
 # This tag requires that the tag ENABLE_PREPROCESSING is set to YES.
