        # #if, #else and #endif) for headers and mainline code,
        # store the ones from the header in libxml2-api.xml, and later

        # mainline code) agree.

        # the variables are not concerned with enabling / disabling of
        # library functions (e.g. '__XML_PARSER_H__'), and we don't want
        # them to be included in libxml2-api.xml, or involved in
        # the check between the header and the mainline code.  To
        # accomplish this, we ignore any conditional which doesn't include
